Description
About the Dress: Ellie Wilde EW38013
Ellie Wilde EW38013 is a long strapless sweetheart mermaid gown built from embroidered sequin mesh with beading throughout. The bodice is structured with visible boning channels set beneath an illusion mesh corset construction, and the back closes with a lace-up corset system. Separate spaghetti straps are included for an alternative look. This is a fully embellished gown that covers the body in sequin and beadwork from the sweetheart neckline straight down to the dramatic sweep train.
Fit & Silhouette
EW38013 fits close to the body from the chest through the hips and knees before opening into a wide flare at the hem. That is the mermaid shape — tight through the torso and thighs, then a sweeping flare at the bottom that creates real movement when you walk. The boned corset bodice holds everything in place without needing a separate strapless bra. The lace-up back lets you dial in the fit precisely at the waist. Ellie Wilde EW38013 is cut for a close, sculpted fit, so sizing up one size is worth considering if you are between sizes or carry your measurements in the hips.
Fabric & Detail
The fabric is embroidered sequin mesh — a sheer mesh base with embroidered sequin and beading layered across it. The illusion panels in the bodice are part of the same sequin mesh construction, so the bodice reads as a decorated corset rather than plain mesh. Boning channels run through the bodice and are visible through the illusion mesh. The beading and embroidery continue from the bodice all the way down the skirt to the hem and train. The sweep train adds length at the back and enhances the flare of the mermaid silhouette.

Style & Occasion
Ellie Wilde EW38013 is designed for prom and formal occasions where a fully embellished, highly structured gown makes a statement. The mermaid silhouette and sequin mesh construction make it a strong fit for prom, pageant competitions, formal gala events, and evening occasions. The sweep train adds drama from behind, which photographs well for grand march and red carpet moments at prom. The six available colorways — Black, Dark Purple, Dusk, Light Gold, Red, and Royal Blue — each give the embroidered sequin a different tone, from understated to bold. Pair it with strappy heeled sandals or pointed-toe heels to keep the silhouette clean. The included spaghetti straps offer a styling alternative if you prefer a bit of shoulder support for dancing. Because the fit is close through the hips, plan for comfortable movement — the flare at the knee gives you room to walk and dance freely.

Frequently Asked Questions
Ellie Wilde EW38013 ships from Marlas Fashions warehouses in Los Angeles and New York. Standard delivery takes 7 to 12 business days from the time your order is placed. If your event date is close, rush shipping options are available at checkout — rush timelines are confirmed at the time of order depending on current stock and carrier availability.
Marlas Fashions ships across the United States and Canada, and also ships internationally worldwide. US and Canadian customers pay no import duties on their orders. International shipments are fully tracked, so you can follow your package from the warehouse to your door.
For prom season specifically, the most common question we hear is whether the dress will arrive with enough time for alterations. The honest answer is that 7 to 12 business days is the shipping window, but it does not include time at a tailor if you need hemming or any other adjustments. A mermaid gown like EW38013 is cut very close through the body, and many customers do take it to a tailor for a quick hem or waist adjustment after it arrives. That tailoring appointment is worth factoring into your timeline.
If you are ordering EW38013 close to prom or another event date, we strongly recommend reaching out before you place your order so we can confirm stock on your color and size and give you a realistic arrival estimate. Availability on specific colorways can shift quickly, especially for popular sizes in Red and Black, and confirming stock upfront avoids any last-minute surprises.
Every dress that leaves Marlas Fashions is inspected before it ships. Ellie Wilde EW38013 is an authorized Ellie Wilde product — you are receiving the genuine gown direct from an authorized retailer with more than 40 years in the business. Tracking information is sent to you once your order ships so you always know where your dress is.
Yes — you can absolutely try on Ellie Wilde EW38013 at home before committing. Marlas Fashions accepts returns, and the return window gives you time to put it on properly, check the fit through the hips and waist, test the lace-up back, and make sure the length works for your height before you make a final decision.
Here is how returns work at Marlas Fashions. You can return EW38013 for a store credit that never expires, exchange it for a different size or color, or return it for a refund with a 30% restocking fee deducted. The store credit option is popular with customers who want to hold onto the value toward another order without committing to the restocking fee.
A few practical points to keep in mind when trying on the dress at home. First, put it on over the undergarments you plan to wear to the event — a mermaid gown that fits beautifully over the right undergarments can feel slightly different with the wrong ones. Second, the lace-up corset back is meant to be tightened while you are wearing the dress, not before. Have someone tighten the lacing once you are in it so you get an accurate read on how the fit feels through the waist. Third, try it on with the heels you plan to wear. The length and the sweep train will look and feel different depending on heel height, and that affects whether you will want a hem adjustment.
If the fit is close but not quite perfect — say the waist needs to come in slightly or the hem needs shortening — those are both straightforward tailoring jobs on a sequin mesh gown. A tailor familiar with structured gowns can handle both without disturbing the embroidery or beading.
For specific questions about your return or to talk through sizing before you order, text us or reach out on WhatsApp — details are in the concierge FAQ below.
The main thing that separates EW38013 from a standard sequin mermaid gown is the construction of the bodice. Most sequin prom gowns put all of their embellishment on the outside fabric and use a plain inner lining. EW38013 uses an illusion mesh corset bodice where the boning channels are visible through the sheer mesh — the structure of the dress is part of the visual design. When you look at the bodice, you are seeing the architecture of the corset as a design element, not just sequin fabric stretched over a hidden boning. The second difference is coverage. The embroidered sequin and beading run continuously from the sweetheart neckline down through the mermaid skirt all the way to the sweep train. There is no plain fabric section on this gown — it is embellished from top to hem. That level of coverage reads significantly more finished and substantial in person and in photographs compared to gowns that are sequined only on the bodice or only on the skirt. The third point is the included spaghetti straps. EW38013 ships with separate spaghetti straps that you can attach if you want shoulder support for dancing or prefer the look of a strapped silhouette. Most strapless gowns do not include this option — it gives EW38013 two distinct styling possibilities from a single purchase. Finally, the six-colorway range is broader than most comparable styles.
The back of EW38013 closes with a lace-up corset system. A ribbon or cord runs through a row of eyelets or loops down the center back of the gown, and you tighten it by pulling the lacing and tying it off. Boning channels run through the bodice and are visible through the illusion mesh — those bones keep the structure firm even as you adjust the lacing.
The practical benefit of a lace-up corset back over a zipper is adjustability. You can loosen or tighten the back by an inch or more depending on how the lacing is set. This matters with a mermaid gown specifically because the fit through the hips is the most critical measurement — if the hip measurement is slightly larger or smaller than the size chart suggests, the corset back gives you real room to compensate.
For getting into the dress, it is easiest to step in from the top with the lacing loosened significantly, then have someone tighten and tie the back while you are wearing it. Trying to tighten it on yourself is difficult because the tension needs to be even from top to bottom. Plan for a few minutes with a friend or family member when getting dressed.
Because the boning holds the bodice structure firmly, EW38013 does not require a separate strapless bra. The corset construction is the support system. The included spaghetti straps are available if you want additional shoulder security, particularly during extended dancing.
EW38013 works well as a statement gown for a lead — a prom queen, a quinceañera honoree, or the main person in a formal party — while the court or damas wear complementary styles rather than identical matches. The six available colorways make coordination flexible. A group wearing Ellie Wilde gowns in Dark Purple or Royal Blue while the lead wears Red, for example, creates a clear visual hierarchy without the group looking mismatched.
If you want exact coordination across a larger group, Marlas Fashions carries multiple Ellie Wilde styles in overlapping colorways, so it is possible to put together a coordinated look across different silhouettes in the same color family. Text or WhatsApp the Marlas concierge team with your group size, target colorways, and event date — we can pull up what is currently in stock across sizes and confirm availability before anyone places an order. Contact details are in the shipping FAQ above. The key thing with group orders is confirming stock on all sizes at the same time, because popular colors in specific sizes sell through faster than others.
Ellie Wilde EW38013 is available in sizes 00 to 16. Sizing on a mermaid gown like EW38013 is driven primarily by the hip measurement because the fit is closest through the hips and thighs. The corset lace-up back gives some flexibility at the waist, but the hip seams are fixed — there is no adjustment there.
The general guidance for EW38013 is to measure your bust, waist, and hips before ordering and compare against the Ellie Wilde size chart. If your hip measurement puts you between two sizes, order the larger size. You can always have the waist taken in by a tailor, but letting out the hip seam on a fully beaded sequin gown is more involved. Sizing up at the hip and adjusting down at the waist is a much cleaner tailoring job.
If you are closer to a plus size or carry your measurements in the lower body, the upper end of the size range up to size 16 is available, and the lace-up back accommodates a range within each size.
For the most accurate fit advice specific to your measurements, reach out to our team: text +1 416-536-2956 or WhatsApp +1 213-868-3131. We can walk through the Ellie Wilde size chart with you and recommend the right size for EW38013 based on your actual measurements.
EW38013 is designed for prom as its primary occasion, but the level of embellishment and structure makes it appropriate for a range of formal events. Pageant competitions are a strong fit — the fully beaded embroidered sequin coverage from neckline to train reads as a competition-level gown. Formal gala events and evening occasions where a statement long gown is appropriate are also realistic fits.
The gown is not appropriate for wedding guests. The illusion mesh bodice construction, the visible lace-up corset back, and the overtly form-fitting silhouette push it outside the modesty range for wedding guest wear under Marlas Fashions guidelines. It is also not a standard choice for mother-of-the-bride or bridesmaid roles.
For formal dances other than prom — military ball, black tie events, or evening galas — the level of embellishment is appropriate and the mermaid silhouette works well on formal dance floors. If you are considering EW38013 for an event other than prom and want a second opinion on whether it fits the dress code, the Marlas team is happy to advise.
EW38013 has a fully boned corset bodice, which means it provides its own bust support. You do not need a separate strapless bra with this gown — the boning and the lace-up back create the structure that holds the bodice in place. This is one of the functional advantages of a corset construction over a standard boned bodice.
For the lower half, a smooth seamless brief or thong is the best choice under a mermaid gown. Because the sequin mesh fabric sits close to the body through the hips and thighs, any panty line or fabric bulk will show through. Low-waisted or hipster-cut options work best to avoid a visible waistband line beneath the sequin.
Avoid shapewear that adds significant compression or thickness at the hips — the fit in the hip area of a mermaid gown is sized to the body, not over shapewear. Light smoothing shorts that end at or above mid-thigh are fine if preferred.
The included spaghetti straps can be attached at the shoulders if you want additional support during extended dancing. They do not change the undergarment needs but give some added shoulder security for active wear.
