Description
About the Dress: Ellie Wilde EW37070
Ellie Wilde EW37070 is a long sequin mermaid gown covered entirely in beaded sequin from the neckline to the hem. The sweetheart neckline is held up by thin spaghetti straps, and a sheer illusion mesh panel runs through the bodice and waist cutout, creating a subtle see-through detail that catches the light. The dress finishes with a small train at the back. Ellie Wilde EW37070 is available in Black, Dusk, Emerald, and Purple Rain.
Fit & Silhouette
EW37070 follows a true mermaid silhouette — it fits close to the body through the bust, waist, and hips, then gradually flares out below the knee into a dramatic hemline with a train. The fit is sleek and body-hugging from top to bottom. The sweetheart neckline creates a defined, lifted shape across the chest. Spaghetti straps keep the neckline in place without adding bulk. This cut works best when ordered to your measurements; we recommend referring to Ellie Wilde's size chart and paying close attention to hip measurements before placing your order.
Fabric & Detail
The entire surface of EW37070 — from the bodice down to the flared hem — is covered in sequin and beading, so the dress catches light from every angle when you move. The sequin construction gives the gown a full, luminous texture rather than a flat sparkle. A sheer mesh panel is inset into the bodice and waist area, creating an illusion cutout that adds visual interest without changing the silhouette. The back of the dress is dramatically open, bare well below the waistline, with no boning or corset closure — just clean open construction.
Key Features
- Fully beaded sequin construction covering the entire gown
- Sheer illusion mesh panel in the bodice and waist cutout
- Sweetheart neckline with thin spaghetti straps
- True mermaid silhouette fitted through the hips, flaring below the knee
- Dramatic open back bare to well below the waistline
- Small train at the hem
- Available in Black, Dusk, Emerald, and Purple Rain
Style & Occasion
Ellie Wilde EW37070 is designed for high-impact formal events where you want a fully-sequined gown that commands attention. It is a strong choice for prom, formal dances, gala events, and evening occasions where a dramatic silhouette and full-surface sparkle are appropriate. The open back and sleek mermaid line make this a statement look suited to someone comfortable wearing a body-hugging, heavily embellished gown. Style it with strappy heeled sandals — metallic gold or silver work with every colorway. Keep jewelry minimal: the sequin surface and illusion mesh do the visual work. A simple drop earring or small stud is usually enough. If you are considering two colorways, Emerald reads as a bold jewel tone in person, Black is classic and versatile, Dusk photographs with a warm champagne-beige tone, and Purple Rain delivers a deep violet. All four are available at Marlas Fashions with tracked shipping to the US, Canada, and internationally.

Frequently Asked Questions
The four colorways in Ellie Wilde EW37070 each read differently in person than they can on screen, so it is worth understanding what you are looking at before you commit.
Emerald is a true, saturated jewel-tone green — rich and bold. In person it has more depth than it sometimes shows in photography, especially under ballroom or event lighting, where the full-surface sequin picks up the green and amplifies it. If you want to stand out and you are comfortable in a strong color, Emerald is the most dramatic choice in this group.
Black is the most versatile option. Black sequin is a classic formal choice that photographs well in almost any lighting and works with virtually any shoe, bag, or jewelry you already own. It is also the most forgiving in terms of showing smudges or transfer from other surfaces during wear. If you are unsure or want a safe, polished look, Black is the reliable pick.
Dusk can appear differently depending on your screen calibration. In person it reads as a warm, muted champagne-beige tone — softer and less saturated than it sometimes looks in photographs where it can appear slightly pinkish or golden depending on the lighting used for the shoot. If your screen is not color-accurate, Dusk can look cooler or warmer than reality. It is a sophisticated neutral that pairs well with gold accessories and warm-toned skin, but if you are expecting a bright champagne, manage expectations — it is a quieter, dusty tone.
Purple Rain is a deep violet-purple. In person it is rich and saturated, leaning more toward true purple than lavender. Under event lighting the sequin reflects the purple beautifully. If you love jewel-tone purple and want something a bit different from the typical prom palette, Purple Rain delivers.
One thing that applies to all four colorways: the fully-sequined construction means the color will shift visually depending on how you move and where the light hits. In dim lighting, the dress reads darker and more dramatic. Under bright spotlights or flash photography, all four colorways become noticeably more luminous. This is normal for full-surface sequin and is part of what makes the gown striking.
If you have a venue in mind, think about the lighting there. If you are comparing two colors and genuinely cannot decide, most shoppers find that ordering the colorway they are most drawn to first is the right call — the sequin construction photographs beautifully in all four shades. Reach out to us if you have a specific color-matching question and we will do our best to help.
Ellie Wilde EW37070 is built for high-impact formal occasions where a fully-sequined, body-hugging mermaid gown is appropriate and expected. Here is how it maps to specific events.
Prom is the primary fit. The dramatic open back, full-surface sequin, mermaid silhouette, and train are exactly what prom is designed for. This gown will photograph exceptionally well under event lighting and makes a strong statement on a dance floor. All four colorways — Black, Dusk, Emerald, and Purple Rain — are well suited to prom.
Formal dances and evening galas are also a natural fit. If you are attending a formal gala, charity dinner, or evening event with a formal dress code, EW37070 delivers the right level of embellishment and silhouette. The sleek mermaid line reads as polished and deliberate rather than costume-like, which makes it appropriate for adult formal events as well as student formals.
Evening events more broadly — awards ceremonies, pageant-adjacent events where a sequined gown is suitable, or formal photo shoots — are occasions where this dress works well. The fully-beaded sequin surface catches light exceptionally under professional lighting, which is part of why this silhouette and fabric combination is popular for events where photos matter.
As a wedding guest, this gown suits evening receptions and black-tie celebrations best, where its dramatic beading and open back are a natural fit. The dramatically open back, figure-hugging silhouette, and full-surface sparkle give this gown a bold presence that suits evening receptions and black-tie galas beautifully; as a wedding guest, it works best at glamorous evening or black-tie celebrations where statement dressing is welcome. For a formal wedding as a guest, the open back is worth keeping in mind — it suits evening receptions and black-tie celebrations best, where dress codes tend to be more relaxed about dramatic styling.
Military ball is also not a fit — that category requires a covered back, and EW37070's back is fully open to well below the waistline.
If you are attending an event and are unsure whether EW37070 is appropriate for the specific dress code, the key questions are: Is a full-sequin gown allowed? Is an open back acceptable? If yes to both, the dress is likely a strong choice. If the dress code leans conservative or modesty is a requirement, this particular silhouette may not be the best match, and we are happy to suggest alternatives from Ellie Wilde's collection if you reach out.
Because EW37070 is fully covered in beaded sequin over a mesh and lining construction, it requires careful handling to maintain the surface over time.
For cleaning, dry cleaning is the safest option for a fully-sequined gown. Do not machine wash or hand wash — water and agitation can loosen sequin attachments or cause the lining to distort. If the dress picks up a small spot during wear, blot it gently with a dry cloth and take it to a professional dry cleaner with experience in beaded formal wear as soon as possible. Mention the sequin and the mesh illusion panel so they handle it appropriately.
For storage, hang the dress on a padded hanger in a breathable garment bag. Avoid plastic bags that trap moisture. Keep it away from direct sunlight, which can affect the colorway over time. If you are storing it long-term after the event, wrap it loosely in acid-free tissue to protect the sequin surface.
For travel, lay the dress flat in a hard-sided garment bag or suitcase if possible. Sequined gowns can snag on zippers and rough surfaces, so keep it in a garment bag inside the suitcase. The train will need to be folded carefully — fold loosely and place tissue between layers to minimize creasing. Light steaming from a distance can release travel wrinkles, but do not iron directly on the sequin surface.
Because EW37070 is fully sequined from the sweetheart neckline to the train, the dress is doing most of the visual work on its own. The goal with accessories is to complement the gown without competing with it.
For shoes, strappy heeled sandals are the most natural pairing with a mermaid gown and spaghetti straps. Metallic silver or gold work with every colorway in this style — silver tends to read cleaner against Black, Emerald, and Purple Rain, while gold warms up Dusk beautifully. A block heel or kitten heel is a practical alternative if you plan to dance, since a mermaid skirt does limit stride and you will be on your feet for several hours.
For jewelry, keep it minimal. The sequin surface and the illusion mesh bodice are visually strong on their own. A simple drop earring or small stud is usually enough. If you want to add a necklace, a thin delicate chain sits well against the sweetheart neckline without crowding it. Avoid chunky statement necklaces — they fight with the neckline rather than work with it.
For a bag, a small metallic clutch in silver or gold keeps the look cohesive and formal. Avoid large bags that interrupt the silhouette of the gown.
A mermaid silhouette like EW37070 is one of the most figure-defining cuts in formal wear, and it works best for specific body types and proportions.
This dress is most flattering on hourglass figures or those with well-defined waist-to-hip ratios, because the fit-through-hip construction relies on natural curves to fill out the silhouette. If the hip measurement is smaller, the flare at the hem can look less dramatic than it does on the model.
For taller figures, the full mermaid length and train read especially well because there is enough height to show the full silhouette before the flare begins. On petite frames, a mermaid can shorten the visual line — if you are petite, consider the fit carefully and try it on or check measurements before ordering.
The sweetheart neckline is broadly flattering across bust sizes because it frames and lifts. The spaghetti straps add structure without adding visual bulk at the shoulder. The illusion mesh bodice panel adds visual interest at the waist area, which draws attention to that section of the silhouette.
Because the gown fits close through the hips with no stretch seams at the skirt, hip measurement accuracy is critical when selecting a size. We recommend measuring at the fullest point of the hips and comparing to the Ellie Wilde size chart before ordering.
Marlas Fashions ships Ellie Wilde EW37070 from warehouses in Los Angeles and New York in the United States, and from Toronto for Canadian orders. Standard delivery takes 7 to 12 business days from the time your order is confirmed. Rush shipping is available if you need the dress sooner — contact us before placing your order to confirm availability and timing for your specific event date.
Shipping is fully tracked to the United States and Canada with no duties charged on US or Canadian orders. International shipping is also available with worldwide tracked delivery. We recommend ordering as early as possible if your event has a fixed date, especially for prom season when demand is highest. If you have a specific date in mind and you are concerned about timing, reach out and we will confirm whether standard or rush shipping is the right option for your timeline. Our concierge team is available by text at +1 416-536-2956 or WhatsApp at +1 213-868-3131.
Marlas Fashions accepts returns on Ellie Wilde EW37070 with three options: store credit that never expires, an exchange for a different size or colorway, or a refund less a 30% restocking fee. To be eligible for return, the dress must be unworn, unaltered, and in original condition with tags attached.
Because this is a fully-sequined gown with a dramatic open back, we strongly recommend ordering your size carefully using the Ellie Wilde size chart before purchasing. The mermaid silhouette and sequin construction mean the dress needs to fit correctly to look and feel right — alterations to a fully-beaded sequined gown are significantly more complex and costly than on a plain fabric gown, and not all tailors will take on sequin work.
If you receive the dress and it does not fit as expected, contact us promptly. We will walk you through your options and help find the best resolution. Store credit is a popular option if you want to try a different size or a different colorway without losing the value of the original order.
Several construction details set EW37070 apart from standard sequin mermaid gowns at a similar price point.
First, the sequin coverage is complete — from the sweetheart neckline all the way to the train, there is no break in the sequin surface. Many dresses described as sequin have solid or chiffon sections at the waist or skirt that interrupt the embellishment. EW37070 does not. The fully-beaded sequin construction means the light reflection is consistent across the entire gown when you move.
Second, the illusion mesh panel in the bodice and waist area is an uncommon detail in this category. Rather than a straightforward strapless or strap-supported neckline, the sheer mesh insert adds a cutout-style visual element that reads as more editorial and less conventional.
Third, the dramatically open back extends well below the waistline, which gives the back view of the gown equal visual impact to the front. This is a detail that photographs exceptionally well and tends to make a significant impression at events where you will be photographed from multiple angles.
Finally, four distinct colorways — Black, Dusk, Emerald, and Purple Rain — mean you can choose based on your event palette and personal tone preference rather than being limited to one option. Ellie Wilde's color execution on sequin fabric is consistent across the range.
