Description
About the Dress: Ellie Wilde EW37207
Ellie Wilde EW37207 is a long fitted mermaid prom gown built around a structured illusion corset bodice and a dramatic tiered glitter tulle ruffle skirt. The sweetheart neckline sits at the front of a sheer mesh center-front panel that runs straight down through the bodice, showing the vertical boning channels underneath. The skirt flares below the knee into layered ruffles with embedded glitter throughout the tulle, and the back sweeps into a slight train. Available in Bluebell, Dusk, Emerald, Purple, and Strawberry.
Fit & Silhouette
Ellie Wilde EW37207 is a true mermaid silhouette — fitted through the bust, waist, and hips all the way to the knee, then flaring out into the tiered ruffle skirt. The corset bodice has visible boning channels that hold the structure and support the fit without a bra. The full open back is held by narrow spaghetti straps crossing at the back, so the fit at the torso depends almost entirely on the structured bodice. Order to your bust measurement first; a local tailor can take in the waist or hips after the fact. Because the skirt flares at the knee, movement is easier than a straight column gown — you can walk and dance without fighting the fabric.
Fabric & Detail
The bodice is built from a sheer illusion mesh panel with lace floral appliqués placed over it. The appliqués carry beading and hot-stone embellishment that catches the light, and the boning channels run vertically through the sheer fabric. The skirt is glitter tulle — the glitter is embedded in the tulle itself, not a surface coating, so it holds up through a full evening. The tiered ruffle construction of the skirt is the signature design element of Ellie Wilde EW37207: multiple horizontal ruffle layers stack from the knee flare to the hem, finishing with a slight train at the back.

Style & Occasion
Ellie Wilde EW37207 is designed for prom. The dramatic open back, exposed illusion bodice, and floor-length glitter ruffle skirt put it squarely in prom-night territory — this is a statement gown built for a formal dance, not a daytime event. Style it with strappy heeled sandals to keep the focus on the dress; a delicate pendant necklace or drop earrings work better than a statement necklace because the beaded bodice already provides visual interest at the neckline. A small clutch in a metallic tone complements the glitter tulle without competing. The open back means a backless or stick-on adhesive bra is the practical undergarment choice. Marlas Fashions is an authorized Ellie Wilde retailer and carries the full EW37207 color run.

Frequently Asked Questions
Ellie Wilde EW37207 is a floor-length mermaid gown with a tiered ruffle skirt and a slight train, and height alterations are one of the most common requests we hear for this style. The good news is that hemming a tiered ruffle skirt is entirely doable — a skilled formal-wear tailor will trim from the bottom of the outermost ruffle layer and reattach the hem, preserving the layered effect. It takes more time and precision than hemming a plain chiffon skirt, so bring the shoes you plan to wear to your fitting and allow at least two to three fittings for the best result. Budget roughly one to two hours of tailoring time and confirm that your tailor has worked on ruffle-tier gowns before — it is a different skill than hemming a straight skirt.
For the bodice, the corset construction with visible boning channels is actually your friend when it comes to fit. The boning holds the bodice in position, so minor waist and side-seam adjustments are straightforward. Taking in the hips on a fitted mermaid does involve releasing the side seams through the thigh area, which is more work, so order as close to your hip measurement as possible and prioritize the bust when choosing a size. The structured corset bodice cannot easily be let out, only taken in, so if you are between sizes, size up and have the bodice taken in rather than buying small.
The sheer illusion mesh panel on the center front is delicate — if the bodice needs significant structural alterations near that panel, make sure your tailor is experienced with illusion fabrics so the mesh stays smooth and the boning channels stay vertical. The lace floral appliqués are attached to the mesh, not to an inner lining, so any alterations near the appliqués require extra care.
For length: if you are 5'4" or shorter, you will almost certainly need a hem. If you are 5'7" or above, the train may fall exactly where you want it without any alteration. Ellie Wilde designs to a standard height of roughly 5'8" to 5'9" in a 3-to-4-inch heel. Have the dress fitted with your actual prom shoes on your feet, not flats, and pin the hem from the front and the back separately because the train at the back should sit slightly lower than the front.
If you are not sure which size to order or want advice before purchasing, reach out to us — our team is happy to walk through your measurements with you before the order goes in.
Ellie Wilde EW37207 is built for prom. The combination of a full open back, a sheer illusion corset bodice with exposed boning, and a dramatic floor-length glitter tulle ruffle skirt with a train puts this squarely in the category of a statement prom gown — it is designed to make an entrance at a formal dance.
For prom specifically, it covers everything the occasion calls for: floor-length, structured, attention-grabbing, and available in a range of colors so you can match a date or stand out from the crowd. The glitter-embedded tulle skirt catches dance-floor lighting beautifully, and the tiered ruffle silhouette photographs well under event lighting.
For other events, the honest answer is that the styling is quite bold. The full open back down to the waistline and the sheer illusion bodice with visible boning are dramatic design choices that work at a prom or a similar formal dance event. A black-tie gala could work if you want to go bold — the gown has the construction quality for it. For wedding-guest occasions, the open back and exposed bodice suit evening and black-tie receptions best; more covered styles tend to be the better choice for daytime or traditional ceremonies.
If you are considering it for a formal winter dance, a homecoming formal, or a similar high school or college event, the key question is the dress code. If the event calls for floor-length formal attire and bold styling is welcome, EW37207 fits the brief. If the event is business-formal or semi-formal, this gown is over-dressed for the occasion.
The five colorways — Bluebell, Dusk, Emerald, Purple, and Strawberry — give you options depending on the vibe of your event. Dusk is a softer, more muted tone that reads slightly more understated than the brighter Strawberry or Emerald. If you want the drama of the silhouette with a quieter color story, Dusk or Bluebell tend to photograph as more wearable across multiple settings.
Bottom line: this is a prom gown first. It can translate to other formal events where bold styling is welcome, but its design DNA is firmly in the prom category.
Screen colors are always a little different from the real thing, and glitter tulle adds another layer of variation because the embedded glitter shifts the perceived color depending on the lighting. In general, the colors you see on our product pages are shot under studio lighting, which tends to be slightly cooler and brighter than natural or venue light. Strawberry photographs as a warm, saturated pink-red. In person it leans more berry-red than pure pink under warm venue lighting. Emerald is a deep, rich green — it reads consistently across most lighting conditions and is one of the more true-to-photo colors in the lineup. Bluebell is a soft blue-purple that can shift more blue or more lavender depending on whether you are under warm or cool light. Dusk is a muted, dusty rose or mauve tone — it can look almost grey-pink under cool lighting, which some customers love for a more romantic, less candy-bright look. Purple is a mid-depth jewel purple that photographs fairly true. If you are matching to a specific accessory, swatch, or date's outfit, reach out to us before ordering and we can give you a closer read on the specific colorway. For most customers, the best guidance is: if you are drawn to a softer, more romantic look, Dusk or Bluebell; if you want high-impact color, Strawberry or Emerald; if you want a classic jewel tone, Purple.
The construction of Ellie Wilde EW37207 — sheer illusion mesh, lace floral appliqués with beading and hot-stone embellishment, and a glitter tulle skirt — means dry cleaning is the right choice after wearing. Do not machine wash or hand wash. The hot-stone and bead embellishment on the bodice can loosen in water, and the glitter in the tulle is embedded rather than surface-coated, but the mesh panel is delicate enough that agitation is a risk.
For storage, hang the dress in a breathable garment bag on a padded or wide hanger. The tiered ruffle skirt holds its shape better when hanging than when folded. Avoid plastic dry-cleaning bags for long-term storage — they trap moisture. A fabric garment bag is the right choice.
For travel, a hard-shell garment bag or a dedicated dress box is the safest option for a gown with this much structure and ruffle volume. If you need to fold it, place the bodice flat with tissue paper between the appliqué layers and fold the skirt loosely rather than tightly pressing the ruffles flat. Steam — not an iron directly on the fabric — is the best way to release wrinkles in the tulle and mesh once you arrive. Keep the iron away from the hot-stone embellishment entirely; heat can loosen the adhesive bond on hot-stones. A handheld steamer at a low setting, held six to eight inches from the fabric, is the safest approach.
The design of Ellie Wilde EW37207 does most of the visual work — the beaded illusion bodice, the open back, and the glitter ruffle skirt are all competing for attention, so the goal with accessories is to complement rather than compete. For shoes, a strappy heeled sandal in gold, silver, or a nude-adjacent tone keeps the focus on the gown. Platform heels work well with the tiered skirt volume. Avoid an ankle boot or a chunky shoe — the ruffle hem at the floor makes the hem line the visual anchor, and a clean, slender heel looks most proportional. Choose your shoes before your hemming appointment so the tailor can set the length correctly. For jewelry, the beaded and hot-stone bodice means you do not need a statement necklace — the neckline and chest are already heavily embellished. A pair of drop earrings or small hoops at the ear are a cleaner pairing than a chunky statement necklace layered on top of the appliqués. If you want to wear something at the neck, a very fine chain pendant sits below the neckline without cluttering the bodice. For a bag, a small metallic clutch — gold or silver — mirrors the glitter in the tulle and keeps the look cohesive. The open back is a feature of the dress, not a problem to solve, so skip a wrap or shawl unless the venue is cold.
The mermaid silhouette of Ellie Wilde EW37207 works best on bodies with definition through the waist and hip. The structured corset bodice with visible boning creates a defined waist even on torsos that are straighter through the middle — the boning does the contouring work. The fitted hip line through the thigh is the section that requires the most precise sizing; if you carry weight in the hips and thighs relative to your bust, size to the hips and have the bodice taken in. For taller figures, the dramatic tiered ruffle skirt and slight train have full room to unfold — the design is engineered for height. For petite figures, the mermaid flare at the knee can feel a little restrictive in stride until you break it in; plan on a hem and wear the dress for an hour before the event to get comfortable with the stride length. For fuller busts, the corset boning provides support without a bra, but the sweetheart neckline and sheer illusion bodice do not provide the same coverage as a fully lined bodice. If coverage is a priority, this may not be the right choice. For straighter or athletic figures, the boning creates the curve — this silhouette can work very well because the structured bodice builds the shape. The open back is a defining feature, not an afterthought.
Ellie Wilde EW37207 ships in 7 to 12 business days for standard delivery. Rush options are available if your event is coming up quickly — contact us to confirm availability before placing your order if timing is tight.
Marlas Fashions ships from warehouses in Los Angeles and New York for US orders, and from Toronto for Canadian orders. There are no duties or customs fees for customers in the United States or Canada. International orders ship worldwide with full tracking included in every shipment.
If you need to confirm whether your size and colorway are in stock for a specific ship date, reach out to our team before ordering — we can check warehouse availability and give you a realistic timeline. For prom specifically, we recommend ordering as early as possible to leave time for tailoring after the dress arrives. Most local tailors need two to four weeks for formal gown alterations, so factor that into your timeline when you place the order. A dress that arrives three weeks before prom with no time for alterations is a stressful situation that is easy to avoid by ordering early.
We want you to be happy with your purchase. If Ellie Wilde EW37207 does not work for you when it arrives, you have three options: a store credit that never expires, an exchange for a different size or color, or a refund less a 30% restocking fee.
To use any of these options, the dress must be returned in its original, unworn condition with all tags attached. We inspect every dress before it leaves our warehouse, and returns are held to the same standard — any sign of wear, alteration, or damage will affect your return eligibility.
For prom gowns, the most common return situation is a fit issue. This is why we recommend ordering early and resisting the urge to have the dress altered before you have decided to keep it — once a dress is altered, it can no longer be returned. Try it on as soon as it arrives, walk around in it, check the fit through the hips and bodice, and make your keep-or-return decision before scheduling a tailoring appointment.
If you are genuinely unsure about sizing between two options, our team can help you work through your measurements before you order. Reach out to us by text at +1 416-536-2956 or on WhatsApp at +1 213-868-3131 and we will walk through the fit of this specific style with you so you order the right size the first time.
