Description
About the Dress: Ellie Wilde EW35010
Ellie Wilde EW35010 is a long mermaid gown with a sweetheart neckline, heavy lace and beaded embellishment across the bodice and skirt, and a sweep train. The silhouette is fitted through the bust, waist, and hips before flaring dramatically below the knee. Thin spaghetti straps frame the neckline and support the structured bodice. This gown is available in eight photographed colors: Black, Candy Pink, Emerald, Light Yellow, Navy Blue, Royal Blue, Sage Green, and Strawberry.
Fit & Silhouette
EW35010 is cut to contour through the bust, waist, and hips with no ease — the fit is snug and sculpted until the skirt fans out below the knee into a full mermaid flare. The bodice is boned with visible boning channels running through the centre-front panel, which provides structure and holds the sweetheart neckline in place without needing additional support underneath. The sweep train extends past the hem at the back. Because this gown is form-fitting from shoulder to lower thigh, Ellie Wilde recommends ordering by your largest measurement and planning for a tailored fit at the waist and hip. Use Ellie Wilde's official size chart and measure your bust, natural waist, and fullest hip before selecting your size.
Fabric & Detail
The gown is built on a mesh and tulle base and layered with lace throughout. Floral lace appliqués are placed across the bodice and continue down the skirt. Beading and embroidery add texture and depth to the lace surface. The centre-front bodice features a sheer mesh panel with boning channels running vertically — this panel provides structure while showing the construction detail beneath. At the back, a lace-up closure runs the full length of the bodice and sits open, exposing the back for a dramatic look.
Key Features
- Mermaid silhouette: fitted through hips, pronounced flare below the knee
- Sweetheart neckline with thin spaghetti straps
- Lace, beading, floral appliqués, and embroidery throughout
- Boned bodice with sheer centre-front mesh panel
- Lace-up open back with full skin exposure
- Sweep train at the back hem
- Available in 8 colors: Black, Candy Pink, Emerald, Light Yellow, Navy Blue, Royal Blue, Sage Green, Strawberry
Style & Occasion
Ellie Wilde EW35010 is built for high-drama formal occasions. The beaded lace mermaid silhouette and sweep train make it a strong choice for prom, formal dances, black-tie events, galas, and evening occasions. It works equally well for a Sweet 16 or debut where a show-stopping gown is the goal. The open lace-up back and sheer boning panel add an edge that suits pageant competition as well — note the pageant tag is applied pending client confirmation since the gown has heavy embellishment and an open back but no high slit.
For color, Strawberry and Candy Pink read warm and romantic under event lighting, while Emerald, Navy Blue, and Royal Blue photograph richly at galas and black-tie events. Black is a clean, classic option. Sage Green and Light Yellow offer softer contrast and stand out in outdoor or natural-light settings.
Pair this gown with a strappy heeled sandal or pointed-toe heel to extend the leg line and let the train flow cleanly. Minimal jewelry works best — the lace and beading carry the look on their own.

Frequently Asked Questions
Ellie Wilde EW35010 is a fitted mermaid gown, which means the sizing process is more precise than it would be for an A-line or ballgown. The dress is cut to contour through your bust, waist, and hips with very little ease — it is meant to sit snug against the body through the upper thigh before flaring into the mermaid skirt below the knee. That tight, structured fit is what gives the silhouette its shape, but it also means you need to take your measurements carefully before placing an order.
To find your size, measure three numbers: your full bust (around the fullest part of your chest, with the tape parallel to the floor), your natural waist (the narrowest point of your torso, usually an inch or two above your navel), and your fullest hip (typically about seven to nine inches below the natural waist). Use Ellie Wilde's official size chart and compare all three measurements — do not estimate by your usual dress size, because US ready-to-wear sizing and formal gown sizing do not align.
If your measurements fall between two sizes, order the larger size. On a mermaid gown like EW35010, taking in extra fabric at the waist or hip during alterations is straightforward for any bridal or formal-wear tailor. Letting out a gown that is too small is far harder and sometimes impossible without compromising the lace and beading. Err larger.
The bodice is boned, so it provides its own support structure — the boning channels hold the sweetheart neckline in place and keep the bodice flat without needing a strapless bra underneath. The thin spaghetti straps add security at the shoulders but the boning does most of the structural work.
The sweep train adds length beyond the standard floor-length hem. If you are petite or shorter than the size chart's height baseline (typically around 5'9" for formal gowns), plan to have the hem shortened as well as any fit adjustments made. A trained tailor who works with lace and beaded fabrics is the right person for this job — the lace appliqués and beading run through the skirt, so hem work requires careful attention to the embellishment layout.
Build alterations into your timeline. Order your gown as early as possible, ideally three to four months before your event, and book your first fitting appointment roughly six to eight weeks out. This gives you time for fittings, adjustments, and any unexpected delays without stress. If your event date is firm and close, reach out to Marlas Fashions directly to confirm current lead times before ordering.
Ellie Wilde EW35010 was designed with dramatic, formal occasions in mind. The combination of a fitted mermaid silhouette, sweep train, heavy lace and bead embellishment, and an open lace-up back makes this a gown for events where you want the look to carry the room — not blend into it.
Prom is the most direct fit. EW35010 hits every mark for a prom gown: it is long, structured, heavily embellished, and built to photograph well under event lighting. The boned sweetheart bodice and mermaid flare read as classic prom-night glamour, while the open back and lace detailing give it a more fashion-forward edge than a simple satin gown.
Formal and evening events are equally well-suited. If you are attending a gala, charity dinner, awards ceremony, or any black-tie occasion, EW35010 is an appropriate and strong choice. The dress reads as polished and event-ready without looking like a costume — the embellishment is dense but refined, built from lace appliqués and beading rather than rhinestones or glitter.
Sweet 16 celebrations and debut events work well for this gown when the brief calls for something theatrical. If the party has a formal dress code or the vision is a big, dramatic entrance, EW35010 delivers that. It is less suited to a casual Sweet 16 or one with an informal atmosphere.
Black-tie events are a natural fit given the length, construction, and embellishment level. The train and open back add ceremony to the look, which works in formal reception and gala environments.
Pageant settings are another natural fit — the gown's heavy embellishment, dramatic proportions, and open back all align well with pageant competition styling. The one detail that is technically borderline by the strictest pageant classification is the absence of a high slit. If you are shopping for a pageant specifically, we recommend confirming this gown fits your competition's dress-code requirements before ordering.
As a wedding guest, this gown suits evening receptions and black-tie celebrations best. The significant décolletage, sheer boning panel, and fully open lace-up back give it a bold, formal edge that suits evening receptions and black-tie galas particularly well. A different Ellie Wilde style with more back coverage would be a better fit for that occasion.
In terms of who wears this best: EW35010 suits someone who wants a gown that makes a statement. The silhouette is form-fitting and the back is exposed — it is a confident, high-drama choice rather than a modest or understated one.
Ellie Wilde EW35010 is available in eight colors, all of which are photographed: Black, Candy Pink, Emerald, Light Yellow, Navy Blue, Royal Blue, Sage Green, and Strawberry.
Black is the most versatile option — it reads as sophisticated and polished under any lighting and photographs cleanly at both indoor and outdoor events. Emerald, Navy Blue, and Royal Blue are rich, saturated tones that hold up well in ballroom and banquet lighting, making them strong choices for galas, black-tie dinners, and evening proms. The depth of the lace and beading shows clearly against dark backgrounds.
Strawberry and Candy Pink bring warmth and a romantic quality to the look. Both read well under event lighting and photograph with a soft glow. Strawberry in particular has a slightly deeper, berry-red undertone that gives it more visual weight than a pastel.
Sage Green and Light Yellow are lighter, more delicate colorways. They stand out in outdoor or natural-light settings — garden parties, outdoor evening events — and can look fresh and distinctive at prom when most attendees are in jewel tones or black.
All colors are photographed at Marlas Fashions, so you can view each one on the product page before ordering. If you are deciding between two colors and want guidance, contact Marlas Fashions directly to ask about current stock availability and any color nuances that might not be fully visible on screen.
The back of EW35010 features a lace-up closure that runs the full length of the bodice. This is not a hidden zipper with a lace overlay — the back is genuinely open, with the skin visible through and around the lacing. The look is deliberate: it is one of the defining details of this gown and a significant part of its appeal.
The lace-up closure is also functional. Because the back laces up rather than zipping to a fixed size, it gives some flexibility in fit at the back — if your back measurements sit between sizes, a lace-up closure can accommodate minor variation more forgivingly than a zip. This does not replace getting the right size, but it does add a small amount of practical adjustability.
In terms of wearability, the boned bodice does the structural work, so the open back does not mean you lose support — the boning keeps the front of the gown in place. The back exposure means you will need to be comfortable with the look; it is not a gown where you forget the back is open. Undergarments need to account for the open back — a low-back solution or none at all is typically the right approach.
The sweep train extends from the back hem. It adds drama for walking and photography but requires some awareness when navigating a crowded venue floor. Most wearers manage the train comfortably after a short adjustment period.
Because EW35010 is a fitted mermaid gown with a sweep train, footwear choice affects how the silhouette reads and how easy the train is to manage. A strappy heeled sandal or a pointed-toe heel in a neutral — nude, metallic, or black depending on your colorway — is the most practical choice. The heel adds height that extends the leg line below the mermaid flare, and the open or minimal design keeps the focus on the gown rather than the shoe. A chunky or platform heel tends to interrupt the clean line of the mermaid skirt. For jewelry, the lace appliqués, beading, and embroidery throughout the gown carry significant visual weight on their own. A simple approach works best: small to medium stud or drop earrings, a delicate bracelet or cuff, and minimal neckwear. The sweetheart neckline and straps are already a focal point — a heavy necklace competes with rather than complements the bodice. If you want to add a necklace, a very fine chain or a pendant that sits below the collarbone works better than a statement piece. For hair, an updo or pulled-back style emphasizes the open lace-up back, which is one of the standout details of this gown. Wearing the hair down covers the back detail — not necessarily a problem, but worth considering if the open back is part of why you chose this dress.
Most people wearing EW35010 will need at least minor alterations. This is normal for any fitted, structured formal gown — it is not a sign that something went wrong with the order. The gown is cut to a size chart, not to your individual measurements, so the fit straight out of the bag is almost always close but not perfect. The most common adjustments on a mermaid silhouette like this one are waist suppression, hip adjustment, and hem shortening. The boning in the bodice is fixed, so if the bodice fits well at the bust but feels loose at the waist, a tailor can take in the side seams to create a cleaner contour. Hem shortening is particularly important if you are petite — the sweep train is designed for a taller base height, and having it shortened to sit correctly on your frame makes a significant difference in how the gown moves and photographs. Always use a tailor who has experience with lace and beaded formal gowns. The lace appliqués and beading run through the skirt and bodice, so any alteration requires care to avoid disturbing the embellishment layout. A general tailor who mostly works with casual or everyday clothing may not be the right choice for a gown at this level of construction. Plan your alterations appointment for roughly six to eight weeks before your event.
Marlas Fashions ships Ellie Wilde EW35010 from warehouses in Los Angeles and New York. Canadian orders ship from the Toronto warehouse. Standard delivery takes 7 to 12 business days from the date your order ships. If your event date is close, rush shipping options are available — contact Marlas Fashions before placing your order to confirm rush eligibility and current lead times for this specific style. All orders ship with full tracking, so you can follow your package from dispatch to delivery. Shipping is available worldwide, not just to the US and Canada. There are no import duties charged on orders shipped within the United States or to Canada — the price you pay at checkout is the price you pay. For international orders outside North America, delivery timelines and any applicable customs duties or import fees vary by destination country. Marlas Fashions will provide tracking information for international shipments, but customs clearance timelines are outside their control. If you have a firm event date, calculate your order window carefully. Take the 7 to 12 business day shipping window, add time for any alterations (typically two to four weeks for a fitted formal gown), and work backwards from your event date to find the latest safe order date. Ordering as early as possible — three to four months before the event — removes deadline pressure and gives you flexibility if anything needs to be adjusted.
Marlas Fashions accepts returns and exchanges on Ellie Wilde EW35010. When you return a gown, you have three options: store credit (which never expires, so you can use it whenever you are ready), an exchange for a different size or color of the same style or a different style entirely, or a refund to your original payment method less a 30% restocking fee. The store credit option is the most flexible if you are not certain what you want to do yet — it holds the value of your purchase with no expiration, which means you are not under pressure to make a decision quickly. Returns need to be initiated within the return window outlined in Marlas Fashions' return policy — the gown must be unworn, unaltered, and in its original condition with all tags attached. A gown that has been altered cannot be returned, which is one reason to confirm the fit is right before taking it to a tailor. If you are unsure about size when ordering, err toward the larger size (which is easier to alter down) rather than the smaller one. For direct help with a return, exchange, or any fit questions, you can reach the Marlas Fashions concierge team by text at +1 416-536-2956 or on WhatsApp at +1 213-868-3131.
