Description
About the Dress: Ellie Wilde EW38094
The Ellie Wilde EW38094 is a long mermaid prom gown built from embroidered tulle with lace appliqués, sequin accents, and beading and stone details across the bodice and skirt. It features a sweetheart neckline, a structured boning corset bodice with an illusion sheer panel, and spaghetti straps that cross at the back. The gown finishes with a sweep train. Ellie Wilde EW38094 is available in Yellow, Light Blue, and Kelly Green in sizes 00–16.
Fit & Silhouette
EW38094 follows a true mermaid silhouette — fitted closely through the bust, waist, and hips, then flaring out below the knee. The boned corset bodice gives the waist a sculpted, defined shape and holds everything in place. The illusion panel at the bodice sits against the skin and allows the boning channels to show through, which gives the front a refined, structured look. The spaghetti straps provide shoulder support while keeping the neckline minimal. This dress fits close to the body from top to hem, so it rewards accurate measurements.
Fabric & Detail
The base fabric is embroidered tulle — the skirt carries lace appliqués and embroidery that cover the majority of its surface, giving the gown its depth and texture. The bodice is finished with sequin and beading and stone accents that catch the light without overwhelming the lace. The sheer illusion panel at the bust allows the boning structure to read visually and adds a layer of coverage over the sweetheart cut. The full open back is framed by the crossing spaghetti straps, and the gown closes with a lace-up corset back system. The sweep train drapes cleanly from the hem.

Style & Occasion
Ellie Wilde EW38094 works best when you let the gown do the work. The lace-and-embroidery skirt and the boned illusion bodice are already doing a lot — keep accessories minimal. A simple pair of strappy heels, small stud earrings, and an updo that shows off the open back is the strongest approach. The crossback straps read as a detail, so a necklace would compete rather than complement. This gown is designed for prom and formal evening events where a fitted, floor-length silhouette is the right call. The Yellow colorway photographs with warmth and shows well under venue lighting. Light Blue reads cooler and more formal. Kelly Green is the boldest choice and stands out in a crowd. If you are dressing a group or court, these three colorways can coordinate without matching exactly. For tailoring, the lace-up back adjusts to fit within about one size in either direction, and a skilled seamstress can hem the train to the right floor length for your heel height.

Frequently Asked Questions
Yes, and this is actually one of the strongest things about the Ellie Wilde EW38094. Because the gown is available in Yellow, Light Blue, and Kelly Green, a group or court can each wear a different colorway and still look intentional and put-together rather than mismatched. All three colorways share the same embroidered tulle fabric, the same lace appliqué and embroidery coverage on the skirt, and the same boning and beading bodice construction — so when you stand together, the silhouette and texture are uniform even if the colors differ.
If you want a gradient effect, Yellow and Light Blue sit at opposite ends of the warmth spectrum and pair well together, with Kelly Green adding contrast as a third. If you want a more subdued coordinated look, Yellow and Light Blue alone read clean and complementary. Kelly Green tends to stand out most on its own, so if one person in the group wants to be highlighted — say, the lead — Kelly Green is the natural choice.
For a court where everyone matches exactly, any single colorway works. Yellow tends to be the most versatile under a wide range of venue lighting, including warm amber ballroom lights and outdoor evening setups. Light Blue photographs with a cooler, more formal tone. Kelly Green is vivid in photos and in person.
If you are coordinating a group order, it helps to have everyone place their orders at the same time so sizing and lead time can be managed together. Ellie Wilde EW38094 ships from our Los Angeles and New York warehouses, so in-stock pieces typically ship within the standard window. Our team can help confirm stock across colorways and sizes so the group is not caught short. Standard shipping runs 7–12 business days, and rush options are available if the event is close. We recommend placing group orders as early as possible — stock in any single size and colorway can run out, especially peak season.
If you have questions about coordinating a group order or want to confirm availability across all three colorways before committing, reach out directly and we will walk you through the current inventory picture.
The Ellie Wilde EW38094 runs in line with standard Ellie Wilde sizing, which is generally true to US dress sizing but tends to be cut with a close, fitted silhouette in mind — this is a mermaid gown, so it is designed to sit against the body through the bust, waist, and hips. For most people, the best approach is to measure your bust, waist, and hips and compare them directly to Ellie Wilde's published size chart rather than going by the size you typically wear in clothes.
The boned corset bodice is the most structured part of the dress. It gives real shape and support at the waist, but it also means the bodice does not have the same stretch or give that a jersey or chiffon dress would. If your measurements put you between sizes, size up — the lace-up corset back can be tightened to close the gap, and a seamstress can take in a bodice more easily than let it out when working against a structured corset.
The mermaid skirt fits close through the hips and thighs before flaring below the knee. If you have fuller hips relative to your waist, check whether your hip measurement or your waist measurement sizes you into a larger number — fit through the hips matters just as much as fit through the bodice on this silhouette. A dress that is right through the waist but tight through the hips will restrict your stride.
Built-in boning provides all the support the bodice needs. You do not need a separate strapless bra or bustier under this gown — the boning structure is what holds the sweetheart line in place. If you have concerns about the illusion sheer panel sitting against skin, seamless or low-back adhesive undergarments are the most discreet option.
For petite wearers, the sweep train will almost certainly need to be hemmed. Even with a high heel, most people under 5'6" will find the train too long to move comfortably without alteration. Bring the shoes you plan to wear to your fitting so the seamstress can hem to the right length. The lace appliqué on the skirt hem means hemming should be done by someone with formal wear experience — a hem cut through the lace pattern without matching it will show.
For taller wearers, the sweep train may sit at the right length with or without heels depending on your exact height, so check that at your fitting before committing to a hem.
The Ellie Wilde EW38094 is built for prom and formal evening events. The mermaid silhouette, full sweep train, open back, and embroidered lace skirt put it clearly in prom and formal gown territory. It works well for black-tie-adjacent formal events and evening galas where a floor-length fitted gown fits the dress code.
Because the back is fully open down to below the waistline and the neckline is a low sweetheart cut, this is not a conservative choice. It is designed to make a statement. That means it is not a strong fit for events where coverage is expected — it would not be the right pick for a wedding guest role, a bat mitzvah, or a school confirmation. If the event calls for something more covered, Ellie Wilde has other styles worth looking at.
For prom specifically, the three colorways — Yellow, Light Blue, and Kelly Green — each stand out in a venue setting without looking costume-like. The embroidered tulle and lace appliqué skirt reads formal and detailed under event lighting, and the boning at the bodice gives a polished, put-together look even at the end of a long night.
If you are comparing this to another long formal gown and trying to decide which suits your event better, the key question is whether your venue and dress code support an open back. If yes, EW38094 is a strong contender.
Yes. The boned corset bodice provides full built-in support for the bust. The boning channels run through the sheer illusion panel and hold the sweetheart neckline firmly in place — you do not need a separate bra under this gown. The corset lace-up back lets you adjust the fit at the torso after the dress is on, which also helps dial in the support level. Because the back is fully open to below the waistline, a traditional bra is not an option. The best undergarment approach for most wearers is either nothing additional (the boning is typically sufficient) or a pair of low-back adhesive cups if you want extra security. Seamless underwear in a color close to your skin tone or the gown's lining is the right call for the bottom — nothing that sits above the hip line or shows at the sides. For the illusion sheer panel at the bodice, it sits directly against skin by design. If that is a concern, the panel does have some coverage built in, but it is sheer — that is the intention of the fabric. Wearing a skin-tone adhesive solution underneath the panel is possible but usually unnecessary given the boning structure already there. The spaghetti straps add shoulder stability and help the gown stay in position if you are moving around on a dance floor.
Yes, EW38094 can be altered, but because of the lace appliqué and embroidery on the skirt, the alterations should be done by a seamstress with formal wear or bridal experience. A standard tailor who works mostly with everyday clothing may not be comfortable working around the lace hem pattern.
The most common alteration for this gown is hemming the sweep train. If you are under around 5'6" in heels, the train will need to be shortened so you can walk and dance comfortably. Bring the shoes you plan to wear to the fitting — heel height changes how much needs to come off. The lace at the hem means the seamstress will need to reattach or trim the appliqués carefully to keep the hem looking intentional.
The corset lace-up back adjusts within approximately one full size up or down from the size you ordered, which handles minor fit differences at the waist without a structural alteration. If the bodice needs more significant work — taking in the side seams, for example — that is possible but more involved because of the boning.
Taking in the skirt at the hips is a more complex alteration on a mermaid silhouette and is generally not recommended unless the difference is small. If you are between sizes, size up and use the corset back to bring in the waist.
For a structured mermaid gown, EW38094 is well-suited for an extended event. The boned corset bodice holds its shape and does not require constant adjustment — once it is laced in correctly, it stays in place. The spaghetti crossback straps add stability at the shoulders so the gown does not shift when you move. The mermaid fit is tight through the hips and thighs, which limits stride length. You can walk normally, but you are not going to take wide steps or run in this gown. On a dance floor, the flare below the knee gives you more room to move than the fitted section of the skirt would suggest — the flare starts at roughly knee level, which is enough for most dance styles. The embroidered tulle skirt is lighter than it looks. Tulle has volume without weight, and the lace appliqués do not add significant bulk. The sweep train is the one practical consideration — if you are on a crowded dance floor, you will want to hold it or let people know it is there. Some wearers bustle or pin the train after photos. The boning means the bodice does not compress or give the way a soft dress would, so if you have a long event ahead, make sure the fit is correct before the night starts. A bodice that is laced too tight will be uncomfortable after a few hours.
The Yellow in EW38094 is a warm, medium-bright yellow — not pastel and not neon. Under venue lighting, particularly warm amber or white ballroom light, it reads vibrant and photogenic without washing out. In photos it tends to look slightly richer than it does under cool or natural light. If your event venue has warm lighting, Yellow is a strong choice. Light Blue is cooler and more subdued. It photographs with a softer, more formal tone and reads more classic prom in the traditional sense. Under cool white lighting it stays true to color. Under warm amber lighting it can look slightly more gray-blue than the product image suggests — worth considering for your specific venue. Kelly Green is the most saturated of the three. It is a true medium green, bold and clear. It stands out in a room and photographs very distinctly. If you want to be noticed, Kelly Green delivers that. If you are part of a coordinated group and want one person to stand out, Kelly Green is the obvious choice for that person. For skin tone: warm and golden undertones tend to work well with Yellow and Kelly Green. Cooler undertones tend to work better with Light Blue.

After wearing, have the gown professionally dry-cleaned by a cleaner with formal wear experience — do not machine wash or hand wash embroidered tulle. The lace appliqués, beading, and stone accents are attached at the surface and can be damaged by agitation or soaking. Spot-cleaning a small area is possible with a damp cloth if done gently, but full cleaning should go to a professional.
For storage, hang the gown on a padded hanger and cover it with a breathable garment bag — not a plastic dry-cleaning bag, which traps moisture. The sweep train should be folded loosely inside the bag rather than left to drag. If storing for an extended period, laying the gown flat in acid-free tissue inside a box is better than hanging, which can cause the fabric to stretch at the shoulder straps over time.
For travel, the gown should be transported in a garment bag rather than folded in a suitcase. If air travel is unavoidable, lay it flat across a carry-on overhead if space allows, or use a dedicated dress travel bag that rolls around the hanger. Tulle does wrinkle but usually relaxes when hung — if it does not, a cool-setting steamer held at a distance (not touching the fabric) works on tulle. Do not iron directly on the lace or beading.
