Description
About the Dress: Ellie Wilde EW35011
Ellie Wilde EW35011 is a full-length mermaid prom gown built around a deep V-neckline and spaghetti straps. The entire surface is covered in a sequined floral-leaf appliqué pattern on a mesh ground, so the dress catches light from every angle. It finishes with a sweep train and is available in eleven colors.
Fit & Silhouette
EW35011 follows a true mermaid cut: the bodice and skirt fit close through the bust, waist, and hips, then flare out below the knee into the train. There is no slit. The silhouette is form-fitting from top to hem, so sizing accurately is important — measure your bust, waist, and hips, then compare against the Ellie Wilde size chart. Most customers find the fit runs close to standard sizing. If you are between sizes, sizing up and having the waist taken in by a tailor is the more comfortable route. The deep plunge neckline and open back are defining features of this look, and they sit best on a structured undergarment or fashion tape.
Fabric & Detail
The foundation is a mesh ground fabric covered in dense sequined floral-leaf appliqués across the full surface of the gown. The floral pattern creates texture and dimension while keeping the overall silhouette sleek. Side panels at the waist incorporate mesh cutouts that add a subtle visual break in the embellishment. The back is fully open, with a crisscross lace-up strap closure at the lower back that draws the eye and keeps the fit secure. The sweep train extends from the flared skirt hem.
Key Features

- Full-coverage sequined floral-leaf appliqué on mesh ground
- Mermaid silhouette — fitted through hips, flares below the knee
- Open back with crisscross lace-up strap closure
- Mesh side cutout panels at waist

Style & Occasion
Ellie Wilde EW35011 is designed for prom, formal dances, and evening events where a dramatic, fully embellished look is the goal. The deep V-neckline makes it a strong choice for prom night, and the sequined floral surface means it photographs exceptionally well under event lighting. It works equally well for formal galas and evening occasions. The open back and bodycon mermaid silhouette are bold choices — this gown is not suited for modest dress codes. Seven of the eleven colors have been photographed: Cerulean Blue, Hot Pink, Lavender, Light Blue, Gold, Silver, and Royal Blue. Black, Dusk, Emerald, and Red are also available from the designer but have not been photographed for this listing — contact the Marlas Fashions concierge if you would like more detail on those colorways before ordering.

Frequently Asked Questions
Sizing EW35011 carefully is worth the extra few minutes because the mermaid cut is fitted from the chest all the way down to the knees. Any gap or tightness in that range will be more noticeable than it would be in an A-line or ballgown.
Start by taking three measurements: your full bust (across the fullest part of your chest), your natural waist (the narrowest point, usually an inch or two above the belly button), and your hips (the fullest point, usually about seven to nine inches below the waist). Write all three down before opening the Ellie Wilde size chart.
Ellie Wilde sizes generally run close to standard US sizing, but the mermaid cut in EW35011 leaves very little ease through the hips and thighs. If your hip measurement puts you in a larger size than your bust or waist, size to your hips. The waist and bust can be taken in by a tailor far more easily than the hip seam can be let out — and on a heavily embellished sequin gown, a tailor working on the waist is a manageable alteration, while trying to add fabric at the hips is much harder.
If you are right on the border between two sizes, go up. EW35011's floral sequin surface also means there is minimal stretch in the fabric — you want room to move, especially if you plan on dancing.
For height, the gown is designed for someone around 5'8" to 5'9" with heels. If you are shorter, plan to hem the train. If you are taller, order early so there is time for the hem to be adjusted if needed.
The deep V-neckline and open back both depend on a clean fit through the torso — if the bodice is too large it will gape at the neckline and at the back opening. This is another reason to avoid sizing up more than one size; if you do need to go up, budget for a bodice adjustment as well.
For personalized sizing guidance specific to your measurements, the Marlas Fashions team is happy to help. Text or WhatsApp the concierge at +1 416-536-2956 or +1 213-868-3131 and have your three measurements ready — the team can cross-reference the Ellie Wilde chart and advise on the best size for EW35011 specifically.
Ellie Wilde EW35011 is a high-impact, fully embellished evening gown, and it is designed for occasions where that level of drama is expected and welcomed.
It is an excellent prom dress. The deep V-neckline, sequined floral-leaf surface, open back, and sweep train hit all the marks for a standout prom look. It photographs extremely well under event lighting, and the mermaid silhouette is one of the most popular prom shapes precisely because it is sleek and show-stopping.
Beyond prom, EW35011 is well suited for formal galas, evening events, and formal dances where a floor-length gown is appropriate and the dress code allows for bold, attention-drawing choices. The full-surface sequin coverage and open back give it a real evening-event presence.
There are also some occasions where this gown is not the right fit. The combination of the deep plunge V-neckline, the fully open back, and the bodycon mermaid silhouette makes it overtly evening-forward and unsuitable for events with a modest dress code. As a wedding guest it suits evening and black-tie receptions best; if the couple has requested covered or conservative attire, a more modest style would be the better choice. It is similarly not suited for a mother-of-the-bride or mother-of-the-groom role.
For quinceañera or Sweet 16 celebrations, EW35011 could work in a setting where the guest wants to make a statement, but it is not the traditional choice for the guest of honor at those events — the styling is evening-party rather than ball-gown-formal.
In short: if your event calls for a dramatic, glamorous full-length gown and you are comfortable in a deep V and an open back, EW35011 delivers. If your event has a modest or covered-back requirement, this is not the gown. Every Ellie Wilde EW35011 that leaves our warehouse is inspected by hand before shipping, so the beadwork, seams, and closures arrive exactly as the designer intended. If you are between sizes on the Ellie Wilde EW35011, our team can talk you through the size chart against your own measurements before you order.
Ellie Wilde EW35011 is available in eleven colors: Black, Cerulean Blue, Dusk, Emerald, Gold, Hot Pink, Lavender, Light Blue, Red, Royal Blue, and Silver.
Seven of those eleven colors have been photographed for this listing. You can see Cerulean Blue, Hot Pink, Lavender, Light Blue, Gold, Royal Blue, and Silver in the product images. The Silver colorway appears in both a front-view photo and an editorial image. The editorial shot features two models — only the model on the left (Silver mermaid with matching sequin floral pattern) is wearing EW35011; the other dress in that image is a different style and should not be used as a reference for EW35011's construction.
Four colors — Black, Dusk, Emerald, and Red — are available from Ellie Wilde but have not been photographed in this listing. All four are legitimate colorways from the designer's line, but if you want to see how the sequined floral-leaf pattern reads in one of those specific colors before ordering, reach out to the Marlas Fashions team. The sequin and floral-appliqué surface will look the same in construction across all colorways; the primary difference is the base color and how the sequins catch light in that hue.
If you are deciding between colors, Cerulean Blue, Royal Blue, Silver, and Gold tend to photograph especially vividly because the sequins contrast strongly against those base tones. Hot Pink and Lavender give a softer, more romantic read while still being high-impact.
The back of EW35011 is fully open — the entire back is exposed from the shoulder blades down to the lower back. There is no mesh panel or illusion fabric filling the opening; the back is genuinely bare.
At the lower back, a crisscross lace-up strap closure brings the two sides of the gown together. The straps cross in an X-pattern and tie or lace up to close. This closure both keeps the gown secure and serves as a design detail — the crisscross hardware against the open back is a deliberate styling choice that draws the eye.
Because the back is fully open, traditional bra straps are not an option with this gown. Stick-on adhesive bras, silicone cups, or built-in fashion tape are the most practical solutions. The crisscross closure at the lower back means a low-back adhesive bra is the best fit.
The back view also confirms the mermaid silhouette from behind — the gown stays close through the hips, with the flare beginning below the knee and flowing into the sweep train.
If you have questions about the back fit or closure adjustment, the Marlas Fashions team can walk you through how to adjust the lace-up tension for your specific measurements.
Whether EW35011 needs alterations depends on how well your measurements align with the Ellie Wilde size chart, but it is worth building alteration time into your planning regardless.
The most common alteration on a mermaid gown is hemming the train. EW35011 is cut for a wearer around 5'8" to 5'9" in heels. If you are shorter, a tailor will need to take up the hem so the train does not drag dangerously underfoot. This is a straightforward alteration but takes time, especially on a heavily embellished sequin fabric where the tailor needs to work carefully around the appliqué pattern.
Waist suppression — taking in the waist slightly when you have sized up to fit the hips — is also common and manageable. Bust adjustments are possible but more involved on a structured bodice.
Plan to order your dress at least ten to twelve weeks before your event. Shipping from Marlas Fashions takes seven to twelve business days, and rush options are available if your timeline is tighter. Once the dress arrives, leave two to four weeks for a tailor consultation, fitting, and pickup. Booking a tailor before the dress arrives is a good idea, especially during prom season when alterations appointments fill quickly.
Bring your shoes to every fitting — heel height directly affects where the hem and train should fall. On a mermaid gown the hem is not adjustable after the fact without a full re-hem, so getting it right at the first fitting saves a second round.
The deep V-neckline and fully open back rule out most conventional bras with EW35011. The best options are a low-back adhesive bra or silicone cups, both of which provide lift and shape without visible straps at the back or front.
For the neckline, a plunge adhesive bra that follows the V-shape of the bodice will give the cleanest line. Make sure the adhesive bra is rated for the depth of the plunge — not all adhesive styles are cut low enough for a deep V.
Fashion tape is a useful backup even if you are wearing an adhesive bra. It helps keep the V-neckline flat against your body when you move, especially on the dance floor. A few strips along the inner edge of the neckline are usually enough.
For the bottom half, seamless underwear or a thong in a color close to your skin tone (or close to the dress color) is the standard choice under a fitted mermaid silhouette. The sequin surface of EW35011 is dense enough that it does not show lines dramatically, but a smooth base is always the safer option.
Compression shapewear that extends through the hips can also help the mermaid fit look seamless, and it adds a small amount of smoothing under the tight skirt. Make sure any shapewear you try ends below the flare point of the skirt — anything that bunches at the knee will affect how the flare sits.
Marlas Fashions ships Ellie Wilde EW35011 from warehouses in Los Angeles and New York for US orders, and from Toronto for Canadian orders. All shipments are fully tracked.
Standard delivery takes seven to twelve business days from the date your order is confirmed. Rush shipping is available if you need the dress sooner — contact the Marlas Fashions team when placing your order to ask about rush options and current timelines.
US orders ship with no duties or import fees. Canadian orders also ship duty-free from the Toronto warehouse. International orders ship worldwide with full tracking; international customers should check local customs rules for their country, as import duties vary by destination.
For prom and formal event orders, Marlas Fashions recommends ordering as early as possible — ideally ten to twelve weeks before your event — to leave time for shipping, any alterations, and a final fitting. During peak prom season, giving yourself extra lead time is especially worthwhile.
If you have questions about your specific shipping timeline or need to confirm availability of a particular color before ordering, the Marlas Fashions team is ready to help.
Marlas Fashions accepts returns and exchanges on Ellie Wilde EW35011 in line with the standard policy.
You can return the dress for store credit (which never expires), exchange it for a different size or color, or request a refund minus a 30% restocking fee. To be eligible, the dress must be returned in its original, unworn condition with tags attached.
Store credit is the most flexible option if you are not sure yet what you want in exchange — it stays on your account indefinitely and can be applied to any future order.
If you received the wrong color or size, or if there is a quality issue with your order, contact the Marlas Fashions team as soon as the dress arrives. The team will walk you through the fastest resolution.
For exchange requests during busy prom season, acting quickly after delivery is important — popular sizes and colors can sell out, and an early exchange request gives you the best chance of getting exactly what you need in time for your event.
If you have questions about whether a specific return or exchange situation qualifies, reach out before sending anything back so the team can confirm the process for your order.
