Description
About the Dress: Ellie Wilde EW37012
Ellie Wilde EW37012 is a long, strapless, sweetheart-neckline fitted gown built around an illusion mesh corset bodice. The bodice features visible boning channels through a sheer mesh panel, beaded sweetheart cups, and a wrap-style ruched waistband — all working together to give you a structured, figure-defining fit from bust to hip. A dramatic high front slit and a sweeping train finish the silhouette at the hem. This gown is available in seven colors: Black, Red, Sakura Pink, Light Yellow, Periwinkle, Dark Purple, and Navy Blue.
Fit & Silhouette
EW37012 fits close through the bust, waist, and hips — a true fitted silhouette that skims the body all the way down, then opens into a slight flared sweep at the hem with a full-length train. The ruched waistband wraps the midsection and smooths the transition between the corset bodice and the lower skirt. The high front slit gives you freedom of movement and adds to the dramatic effect. This is not a fitted — there is no tight-to-knee flare; the slit is the design feature. The sweetheart neckline is defined by a clear dip at the center front, framed by beaded cups that give the bustline shape and lift.
Fabric & Detail
The base fabric is stretch jersey — smooth, slightly shiny, and firm enough to hold the fitted silhouette without going stiff. The bodice incorporates a sheer illusion mesh panel that reveals the structural boning channels underneath, creating the corset effect you can see from the front and sides. Beading runs along the sweetheart cups, adding texture and a refined sparkle at the neckline. The back (visible in position 2) is fully open above a lace-up crisscross closure, which also functions as the primary fit adjustment point. The illusion mesh in the bodice is a structural panel — it covers the majority of the bodice, not just a trim strip — which is why the illusion tag applies here.

Style & Occasion
Ellie Wilde EW37012 is designed for prom, formal dances, and evening events where you want a gown that makes a statement without relying on heavy embellishment. The combination of the open back, high slit, and illusion corset bodice gives it an overtly bold, sleek look — it is built for prom night and formal occasions where that level of drama is exactly right. It pairs well with strappy heeled sandals, minimal jewelry, and a small clutch — the dress carries the look on its own. For a coordinated group or court, solid-color gowns in any of the seven available shades create a clean lineup that photographs well together. The full open back and high slit give this gown a formal evening sensibility; as a wedding guest, it pairs well with an elegant wrap or tailored stole for a polished look.

Frequently Asked Questions
The most important accessory decision with EW37012 is your shoes, because the high front slit means your footwear is visible a lot of the time. A strappy heeled sandal in metallic gold, silver, or a nude tone works with every colorway — it keeps the eye moving upward rather than stopping at the foot. If you want to stay in color, match your shoe to the dress or go one shade deeper. Block-heel sandals are a practical choice for dancing without sacrificing the look. Pointed-toe pumps in black or nude work well with the Black and Dark Purple options in particular.
For jewelry, the beaded sweetheart cups already add detail at the neckline, so you do not need a necklace — and a necklace competes with the beading rather than adding to it. Instead, choose statement earrings: long drop earrings in crystal, gold, or a gemstone that picks up your color work very well here. If you want to wear a necklace, keep it very minimal — a thin chain with a small pendant sits below the beaded edge without overlapping.
A slim cuff or a stack of thin bangles on one wrist is enough for the arm. Avoid chunky bracelets that compete visually with the structured bodice.
For a bag, go small. The gown is the statement, so a small metallic clutch or a simple satin box bag in a matching or neutral shade is the right scale. Avoid a crossbody — the open back means straps sit awkwardly and interfere with the lace-up closure.
If you are wearing a crown or tiara for prom court, a simple updo works better than loose hair because it shows off the open back and the illusion bodice from every angle. A sleek low bun or a braided updo framed with a few face-framing pieces is a strong choice.
Hair up also means the lace-up crisscross closure detail at the back reads cleanly in photos, which is one of the standout features of this gown.
EW37012 is built to create definition at the waist and lift at the bustline, which benefits a wide range of body types — but it works differently depending on your proportions, so here is a breakdown.
If you have a more straight or athletic frame, the wrap-style ruched waistband creates the illusion of a defined waist where the fabric gathers and cinches. The fitted stretch jersey clings smoothly through the hips, and the high slit adds a vertical line that makes the leg look longer. The result is a silhouette that reads as hourglass even if your natural measurements are more even.
If you have a fuller bust, the beaded sweetheart cups and structured boning channels give you real support without needing straps. The sweetheart neckline is one of the most flattering neckline shapes for a fuller bust because it frames the décolletage and holds the shape of the cup. The boning keeps everything in place so you are not adjusting the dress throughout the night.
If you carry more volume through the hips and thighs, the stretch jersey moves with you rather than pulling across the hip seam. The fitted silhouette through the hip is intentional — this is a sleek gown, not a forgiving one — so sizing up and having it taken in slightly at the waist gives you the best result if you are between sizes.
If you are petite, the high slit and long train work in your favor because both create vertical length. The train may need to be bustled for dancing if you are on the shorter side, which is a simple alteration.
If you are taller, the full-length train sweeps dramatically behind you and the gown hits the floor at the right proportion without needing to be lengthened.
For anyone unsure about fit, the lace-up crisscross closure at the back gives you roughly one to two inches of adjustability at the torso, which makes this a forgiving gown if your measurements sit between sizes at the waist or ribcage.
Ellie Wilde EW37012 ships in 7 to 12 business days as a standard timeline. Rush shipping is available if you need the gown sooner — reach out to the Marlas team to confirm rush availability and current lead times before placing your order.
US orders ship from our Los Angeles or New York warehouses depending on stock location. Canadian orders ship from our Toronto warehouse, and there are no duties or import fees on US or Canadian deliveries. International orders ship worldwide with full tracking provided at the time of dispatch.
If you have a specific event date, it is always a good idea to share it when you contact us so we can confirm whether the standard window works or whether rush is the right call. Prom season creates higher demand, so ordering early gives you the most flexibility for alterations as well. Every Ellie Wilde EW37012 that leaves our warehouse is inspected by hand before shipping, so the beadwork, seams, and closures arrive exactly as the designer intended.
If EW37012 arrives and the fit or color is not what you expected, you have three options. First, you can return it for store credit — that credit never expires, so you can apply it to your next dress at any point. Second, you can exchange it for a different size or color. Third, you can return it for a refund, which is issued minus a 30% restocking fee.
All three options are available, so you are not locked in. The key is to try the gown on as soon as it arrives, with your planned shoes and undergarments, before any alterations are made. Altered garments cannot be returned or exchanged. Keep all original packaging and tags in place while you are deciding.
If you are between sizes or unsure about the fit before ordering, contact the Marlas team — we can help you choose the better size for your measurements based on the designer's spec chart.
Most fitted prom gowns give you either a corset bodice or an illusion panel — EW37012 combines both in one structural layer. The sheer mesh across the bodice lets you see the boning channels underneath, so the construction itself becomes part of the design. You get the support of a built-in corset and the visual effect of a sheer illusion bodice without needing two separate garments.
The second thing that sets it apart is the back. The full open back above the lace-up crisscross closure is visible in the back photo — it is not a subtle cutout or a small keyhole. The back is the second major design statement on this dress after the front slit.
Third, the seven color options are broad enough that you can get this silhouette in a classic Black or a softer Sakura Pink or Light Yellow, which gives the same structured gown a completely different character depending on the color you choose.
The ruched waistband also adds a detail layer that most similarly priced fitted gowns skip. It creates a transition between the sheer illusion bodice above and the smooth jersey skirt below, so the eye reads the gown as having multiple zones rather than one flat surface.
The back of EW37012 uses a lace-up crisscross closure — you can see the full back clearly in position 2 of the product images. The lacing runs up from the lower back above a fully open back panel, meaning the majority of the back is bare and the lacing itself is the primary closure detail.
This type of closure gives you approximately one to two inches of adjustability at the waist and ribcage. If you are between sizes, you can lace the closure tighter or leave it slightly looser to accommodate your measurements. For the best result, have someone help you lace it at the event — it is easier to get even tension across both sides with a second pair of hands.
The lacing does not replace a zipper, so there is no additional hidden closure. If you need significant size adjustments beyond the lace-up range, a seamstress can take in or let out the seams of the skirt before the lace-up area. Alterations to the bodice are more complex given the boning and illusion mesh panel, so flag any bodice fit concerns before ordering rather than relying on alterations to fix them after.
Yes — the seven available colors make group coordination straightforward. If your court or group wants a cohesive look, you can put everyone in the same silhouette in different colors, or assign specific colors by role. The Black, Dark Purple, and Navy Blue are the richest and most formal options. Sakura Pink, Light Yellow, and Periwinkle read softer and photograph well together when mixed.
Because the gown is the same silhouette across all colors, the group reads as unified in photos even when the shades are different. The high slit and train create consistent visual lines across the group regardless of colorway.
For a court where one person wants to stand out, putting the featured person in Red against a group in Navy Blue or Black is a clean contrast that works at any venue. Contact Marlas if you are coordinating a group order — we can confirm availability across multiple colors and sizes and advise on lead times to make sure everything arrives together.
Ellie Wilde EW37012 is a fitted gown in stretch jersey, which means it follows the body closely. The designer sizes this gown to standard US formal sizing — measure your bust, waist, and hips, then match the largest measurement to the designer's size chart. Because the fit is close through all three points, you want the size that fits your largest measurement and then size the rest in through the lace-up closure or minor alterations.
Do not size down to get a tighter look — the boning and structured illusion panel are already providing compression. Sizing down too aggressively puts stress on the seams and makes the gown harder to wear for a full evening.
If your measurements fall between two sizes, size up. The lace-up closure gives you adjustment room at the waist, and taking in a fitted skirt is straightforward for any alterations professional. The Marlas concierge team can help you choose between two sizes if you share your measurements — text us at +1 416-536-2956 or WhatsApp at +1 213-868-3131 and we will walk you through it.
