Frequently Asked Questions

Does Ellie Wilde EW37021 have a built-in bra or underwire, and what do I wear underneath?

Ellie Wilde EW37021 has a structured bodice with an interior that provides moderate support at the bust, but it does not include a traditional underwire bra cup. The deep V-neckline and the open lace-up back make it impossible to wear a standard bra with this dress, so most customers go one of two routes. The first option is to use adhesive bra cups or silicone nipple covers. These sit directly against the skin inside the bodice and give a clean line under the fitted front without anything showing at the V or at the back. A good-quality adhesive cup with strong hold — the kind designed specifically for open-back gowns — is what works best here. Look for ones with a strapless, backless design and make sure to test the adhesion with your skin a day or two before the event, since some adhesives react differently depending on skin type or lotions. The second option is to rely on the interior structure of the bodice itself. EW37021 is cut close through the chest and the fitted mermaid silhouette holds the bodice against the body. Customers on the smaller end of the bust spectrum often find the interior structure is enough on its own, especially once the lace-up back closure is pulled in snugly at the waist and back. For the lace-up back: the crisscross closure runs the full length of the open back, and tightening it correctly does a lot of the support work. When you receive the dress, try it on with the lacing loosened first, position yourself, then have someone tighten and tie from the bottom up — this distributes the fit evenly and firms up the bodice at the same time. For undergarments at the bottom half, seamless briefs in a nude or skin-matching tone sit cleanly under the fitted mermaid skirt. Avoid thick seams or lace-edged styles, which can show through the fitted glitter mesh at the hips. Shapewear shorts that extend to mid-thigh can also smooth the line without bunching at the hem of the flared section. If you have any questions about fit specifics or want a recommendation for your measurements before you order, contact Marlas Fashions directly — text or WhatsApp +1 416-536-2956 or +1 213-868-3131 and a member of the concierge team will help you work through it.

What events is Ellie Wilde EW37021 actually right for, and is it too much for a formal dance?

Ellie Wilde EW37021 is built for prom, formal galas, evening events, and high-profile formal occasions where a statement gown is exactly right. It is not subtle — the all-over floral lace appliqués, multi-color sequin beading, glitter mesh, and dramatically open lace-up back make this one of the more embellished, attention-drawing gowns in the EW lineup — and that is the point. For prom specifically, EW37021 is an excellent fit. It hits all the marks that prom shoppers look for: a strong silhouette, a lot of sparkle, a memorable back, and a design that photographs well both in venue lighting and in the outdoor shots people take before the event. The mermaid shape elongates the body and the deep V-neckline creates a confident front profile. In prom venue lighting, the multi-color sequin beading picks up warm and cool tones at the same time, so the dress looks slightly different depending on where you are standing — it stays interesting throughout the night. For a formal gala or evening event, the gown reads as sophisticated rather than purely youthful. The fitted silhouette and the structured lace-up back give it a couture quality that works on adults as well as teenagers. If the event has a formal or black-tie-adjacent dress code, EW37021 meets that standard comfortably. Is it too much for a formal dance? That depends on what you want. This dress is not a background piece — if you wear EW37021, people will notice. If the goal is something understated, this is not the right dress. If the goal is to walk in and have the dress do the talking, this is exactly right. As a wedding guest, this dress works best at evening or black-tie receptions where formal glamour is expected. The fully open back, the deep V, and the overall prom-forward embellishment level make it too much for that context — it would read as competing with the wedding party. For bridesmaids or wedding events, Ellie Wilde has other styles that are a better match. For military balls, the open back disqualifies it under dress-code guidelines that typically require covered backs. For other formal evenings — award ceremonies, charity galas, school formals, cotillions, and debut events — EW37021 works well and delivers a look that holds up across the whole event.

How comfortable is Ellie Wilde EW37021 for dancing and wearing for several hours straight?

The mermaid silhouette of EW37021 is fitted through the hips, which does limit stride compared to an A-line or ballgown. Most customers find they can walk and move comfortably, but dancing that requires wide leg movements — like certain hip-hop styles — is more restricted. Slow dancing, ballroom-style movement, and standard prom-floor dancing are all fine. The glitter mesh base fabric has some give in it, which helps. It is not a rigid structured fabric, so it moves with the body rather than fighting it. The flare below the knee opens up enough room that once the skirt kicks out, you have good mobility from the knees down. The lace-up back is a practical advantage for comfort: because you can control how tight the closure is, you can loosen it slightly during the event if the fit feels restrictive across the waist after a few hours. Bringing a small safety pin or spare lacing material is a good idea for longer events, in case the bow loosens with movement. The spaghetti straps keep the bodice anchored without putting pressure on the shoulders, which most customers find comfortable for extended wear. The floral appliqués and beading add weight to the bodice, but it is distributed across the full surface rather than concentrated in one area, so it does not feel unbalanced.

How does the color look in real life versus the product photos, and which colorway should I choose?

All three colorways of EW37021 — Forest Green/Multi, Royal Blue/Multi, and Ice Blue/Multi — are photographed on the product page, so you can see each one directly rather than guessing from a swatch. That said, photos do not fully capture how the multi-color sequin beading shifts under different lighting. Forest Green/Multi reads as a deep, jewel-toned green in natural light. Under indoor event lighting it picks up warm gold and copper tones through the sequin beading, which gives it a rich, dimensional look. It is the boldest of the three in terms of color saturation. Royal Blue/Multi is vibrant in person — closer to a true cobalt than a navy. The multi-color beading reads more mixed on this colorway, with the blue base making the warmer tones in the embellishment pop more visibly. Ice Blue/Multi has a frosted, almost icy quality in person — lighter and cooler than the product photos suggest on some screens. Under venue lighting with warm tones, it can read as silver-adjacent in certain shots, which photographs extremely well. This is the colorway shown in the close-up detail image. All three colorways use the same multi-color embellishment pattern, so the appliqué and beading design is identical — only the base color shifts. If your venue has warm amber lighting, Forest Green and Royal Blue tend to stand out more. If the venue has cooler or white lighting, Ice Blue/Multi is striking.

How do I care for and store Ellie Wilde EW37021 after the event?

After wearing EW37021, hang the dress on a padded wide-shoulder hanger rather than a thin wire hanger — the weight of the beading and appliqués can pull the fabric if the hanger is too narrow. Store it in a breathable garment bag, not a sealed plastic bag, which can trap moisture and cause fabric discoloration over time. For cleaning, the glitter mesh, floral lace appliqués, and multi-color sequin beading all require dry cleaning rather than home washing. Take the dress to a dry cleaner experienced with beaded and embellished formal gowns — not all cleaners work with heavily embellished dresses, so ask before dropping it off. Point out the beading and the lace appliqués specifically so the cleaner knows to hand-treat those areas. For travel, fold the dress loosely along the natural seams rather than forcing sharp creases into the embellished sections. Lay it flat inside a suitcase if possible. The glitter mesh is more resilient than it looks, but the lace appliqués can snag on rough surfaces, so keep it inside a garment bag or a smooth interior compartment. Minor wrinkles in the mesh base can be removed with a steamer on a low heat setting held a few inches from the fabric — do not iron directly on the embellishment.

What shoes and jewelry work best with Ellie Wilde EW37021?

Because EW37021 already has a lot of visual detail — the glitter mesh, the floral appliqués, the multi-color beading — the best approach for accessories is to complement rather than compete. For shoes, a strappy heeled sandal in gold, silver, or champagne keeps the focus on the dress while adding a clean, finished look at the hemline. Nude or clear heels also work well, especially with the Ice Blue/Multi colorway. Avoid heavily embellished shoes with their own beading or rhinestones — two heavily detailed items at opposite ends of the outfit split the eye in a way that makes both look busier. For jewelry, the deep V-neckline means a necklace can easily over-clutter the front of the dress. Most customers skip a necklace entirely and go with simple drop earrings — a small crystal or pearl drop reads clean against the embellished bodice. If you want a necklace, a very fine delicate chain with a single small pendant is the maximum — anything heavier competes with the V-neckline embellishment. The open lace-up back means the back view is a strong visual feature on its own, so a back-draping necklace is not needed. A thin bracelet or bangle works if you want a wrist accent. For hair, an updo or half-up style shows off both the V-neckline in front and the open lace-up back — wearing hair down covers the back detail, which is one of the standout features of this dress.

How does Ellie Wilde EW37021 fit different body types, and is it flattering if I'm not tall?

The mermaid silhouette of EW37021 works best on customers who are comfortable in a fitted cut through the hips and thighs. It defines the waist, follows the hip curve, and flares at the knee, which creates a long, lean line from top to bottom. Customers who prefer volume or flow through the skirt will find this silhouette less comfortable than an A-line, but for those who want the fitted look it is one of the most flattering shapes available. The deep V-neckline lengthens the torso and draws the eye upward, which works on a wide range of proportions. Customers with a longer torso tend to love the V because it provides visual balance. Customers with a shorter torso can also wear it well since the V creates an elongating illusion. For height: the full-length mermaid with a train reads tallest on customers 5'6" and above, where the flare hits just below the knee and the train sweeps behind. On customers under 5'4", the flare can hit higher on the calf, which shortens the line slightly. Hemming the dress at the waist — raising the waistline seam — is more complex on a mermaid than on a simpler silhouette, so if you need length adjusted, the most practical alteration is taking up the hem. Wearing a heel of 3–4 inches brings the overall length to the right position for most heights.
