Description
About the Dress: Clarisse 810554
The Clarisse 810554 is a long fitted mermaid trumpet gown built on an all-over lace base fabric. It features a sweetheart neckline with a clear front dip, thin spaghetti straps, a fully open back, and a sweep train that trails behind you on the floor. Two colorways are available: Pale Lilac and Black. The Pale Lilac version lets the lace patterning do all the decorative work in a clean, understated way. The Black version adds an all-over hot-stone and glitter scatter across the full dress plus a heavily beaded and floral-appliquéd bodice, making it the more dramatic of the two.
Fit & Silhouette
The Clarisse 810554 is cut to fit tight through the bust, waist, and hips all the way down to the knee, then flares out into a trumpet hem with a sweep train. There is no slit, so the mermaid line stays clean and continuous. The silhouette works well on a range of body types because the lace structure gives the fabric natural compression and definition without feeling restrictive. The sweetheart neckline draws the eye upward and frames the décolletage, while the thin spaghetti straps keep the shoulder line minimal. The back is fully open — the entire back is bare well below the waistline — with a fine crisscross spaghetti strap detail at the upper back that holds the dress in place without blocking the exposure. This is a sleek, body-conscious silhouette designed to stand out.
Fabric & Detail
The base fabric on both colorways is lace — structured enough to hold its shape through the hip and thigh, yet lightweight. In the Pale Lilac, the lace floral motifs create surface interest on their own without any added stones. In the Black, the lace base is covered in a dense hot-stone and glitter scatter across the entire dress, and the bodice adds a layer of beaded and floral-appliquéd detail that catches light from every angle. The sweep train is cut as a continuation of the lace skirt, so it flows naturally and requires no separate panel.
Key Features
- Fitted mermaid trumpet silhouette — tight through hips, flares below the knee
- Sweetheart neckline with visible front dip
- Thin spaghetti straps with crisscross upper-back detail
- Fully open back, bare well below the waistline
- All-over lace base fabric across both colorways
- Pale Lilac: clean lace patterning, no surface stones
- Black: all-over hot-stone and glitter scatter plus beaded floral-appliquéd bodice
- Sweep train included
- Available in extended sizing (size 16 and up included)
Style & Occasion
The Clarisse 810554 suits prom, formal events, evening galas, and any occasion where a bold, body-conscious silhouette is appropriate. The Pale Lilac colorway leans into minimalism — the all-lace surface reads as refined and quiet, making it a strong choice if you want a gown that is elegant without being heavy. The Black colorway with its hot-stone scatter and beaded appliqués is the higher-impact option for a gala or formal evening event where you want maximum presence. Both versions pair best with simple accessories — a small clutch, delicate jewelry, and strappy heeled sandals — because the gown itself carries the look. Because the back is fully open, a standard backless bra or adhesive cups are recommended over a traditional bra.

Frequently Asked Questions
The Clarisse 810554 is a long formal gown primarily designed for prom, but it works well for any formal or evening event that calls for a full-length gown with a bold silhouette.
For prom, it is one of the stronger choices in the Clarisse line because the mermaid trumpet shape and the sweetheart neckline photograph exceptionally well, and the glitter and hot-stone scatter on the Black colorway is exactly the kind of finish that catches the light on a dark dance floor. The Pale Lilac version is softer and more minimal but still reads as a statement gown in a room.
Beyond prom, the 810554 suits formal events, evening galas, and black-tie-adjacent occasions where a long fitted gown is appropriate. If your event has a strict black-tie dress code, both colorways are appropriate in terms of length and formality. The open back adds a level of drama that is very much at home in an evening or gala setting, and pairs well with black-tie and formal events where a more expressive silhouette is welcomed.
The fully open back makes this style best suited for evening, gala, and black-tie settings; for military balls or mother-of-the-bride occasions, a more covered silhouette is usually the better choice. It is also not suited for conservative religious ceremonies. Any event where a covered or modest back is expected is not the right fit for this gown.
The Black colorway with all-over hot stones and glitter is the stronger pick for galas and formal evening events where you want presence and impact. The Pale Lilac version, with its clean lace surface, is better suited for spring formals, prom environments with a lighter color palette, or any occasion where you want to stand out without the weight of surface embellishment.
Both colorways are available in extended sizing, so if you are shopping for prom with a group, there is flexibility in finding the right fit across different sizes in the same style and colorway. For group coordination, the Pale Lilac and Black are different enough that they can work as complementary choices within a court or friend group without clashing — but see the court-matching FAQ below for more detail on that.
The Clarisse 810554 is specifically designed as a fitted mermaid trumpet silhouette, which means the fabric hugs the body from the bust down through the hips and thighs, then opens into a flared hem at the knee. That shape works in two ways: the fitted upper section creates a long, continuous vertical line that visually lengthens the torso, and the flare at the bottom adds movement without adding bulk at the hip.
The lace base fabric plays a big role in how the dress fits different frames. Lace has a natural structure to it — it holds its shape and provides gentle compression across the midsection and hips, which gives the silhouette definition without feeling tight or uncomfortable. Unlike a satin or chiffon gown that drapes loosely, the lace construction on the 810554 provides a mapped-out fit that moves with you.
The sweetheart neckline draws attention upward toward the face and collarbone. On shorter torsos, this helps balance proportions by pulling the eye above the waistline. On longer torsos, the neckline keeps things elegant without making the upper body look too plain. The thin spaghetti straps keep the shoulder line minimal so the neckline stays as the focal point.
Because this gown is offered in extended sizing, the proportions are drafted for a range of body types — not simply scaled up from a smaller sample size. If you are between sizes, sizing up and having minor alterations done at a local tailor is almost always the better approach with a fitted mermaid cut: alterations can take in extra fabric, but a gown that is too small through the hips cannot be let out significantly.
The fully open back adds a dramatic element that suits confident wearers of all body types. The crisscross spaghetti strap detail at the upper back provides security so the gown stays in place, and the open back itself works best when you are comfortable going without a traditional bra. Adhesive cups or a backless bra solution work well here and do not distract from the silhouette.
The sweep train at the hem adds length without requiring any specific height — the train simply lies behind you at any height. Taller wearers will carry the full train more visibly on the floor, while petite wearers may choose to have a few inches hemmed to control the drag, which is a straightforward alteration.
Marlas Fashions ships the Clarisse 810554 from warehouses in Los Angeles and New York within the United States, and from Toronto for Canadian orders. Standard delivery takes 7 to 12 business days from the time your order is placed. Rush shipping options are available if you need the gown sooner than the standard window — you can select that at checkout or contact the team to confirm availability before you order.
Shipping is tracked and fully insured, and you will receive tracking details once your order ships. For US and Canadian customers, there are no duties or customs fees charged — your final price at checkout is what you pay. International orders outside the US and Canada ship worldwide with full tracking, though import duties may apply depending on your country.
If prom or your formal event has a fixed date, plan to order at least three to four weeks in advance of the standard shipping window to leave time for any alterations a local tailor might make after the gown arrives. For rush orders inside two weeks of your event, reach out before placing the order so the team can confirm the timeline is workable for your specific location.
Yes. Marlas Fashions accepts returns and exchanges on the Clarisse 810554. If the fit is not right, you can return the gown for store credit that never expires, exchange it for a different size or style, or request a refund less a 30% restocking fee.
Store credit is often the most flexible option because it gives you full purchasing power toward any other gown or item at Marlas Fashions with no time limit on when you use it. The exchange route works well if you have the right style but need a different size and the timeline allows for a second delivery. The refund option is there if you decide not to proceed at all, and the 30% restocking fee is applied to the original purchase price.
To start a return or exchange, contact the Marlas Fashions team with your order number and the reason for the return. The gown must be in its original, unworn, and unaltered condition with all tags attached. Alterations made to the gown at a tailor prior to trying it on for fit purposes do not affect your return eligibility as long as the gown has not been worn to an event.
If you are unsure about sizing before ordering, the team recommends checking the Clarisse size chart against your actual measurements — bust, waist, and hips — rather than going by your usual dress size, as formal gown sizing often runs differently from ready-to-wear.
The detail that separates the 810554 from most fitted lace gowns at the same price point is the combination of a fully open back with a crisscross spaghetti strap detail rather than a standard keyhole or partial cutout. Most lace mermaid gowns at this level either have a lace-up back that covers most of the back or a small keyhole opening. The 810554 removes the entire back panel — the back is bare well below the waistline — and the only structure at the upper back is the fine crisscross strap that connects to the spaghetti shoulder straps. The effect is dramatically more open than what you see on most competitors in this silhouette.
The second differentiator is the two-colorway approach. The Pale Lilac version is a clean, single-material gown where the lace patterning alone provides decoration. The Black version is a completely different sensory experience — all-over hot-stone and glitter scatter on top of the lace base, plus a beaded and floral-appliquéd bodice. You are essentially getting two gowns in the same cut: one minimal and one maximalist.
The sweep train is also a clean addition — it flows as a natural extension of the lace skirt rather than being an obvious separate tier or overskirt, which keeps the silhouette clean from every angle.
The Clarisse 810554 has a fully open back — there is no zipper, hook panel, or corset lacing running down the center back. The back of the dress is open all the way down to well below the waistline. The only closure at the back is the thin crisscross spaghetti strap detail at the upper back, which is attached to the shoulder straps. This holds the gown in position across the shoulders and keeps the neckline and chest panel stable.
Because there is no back zipper or lace-up panel, there is no adjustment mechanism in the traditional sense. The fit of the gown is determined by how the lace fabric sits through your bust, waist, and hips. This means getting the size right at the point of ordering matters more than on a gown with a corset back that can be tightened or loosened. If the bodice feels slightly loose through the sides or under the bust once the gown arrives, a local tailor can take in the side seams relatively easily on a lace garment. If the gown is too small through the hips or thighs, there is limited ability to let it out, so sizing up and having it altered in is the safer approach.
For undergarment planning: because the back is fully open and bare, a standard bra cannot be worn with this gown. Adhesive cups, a stick-on bra, or a specialized backless solution are the most practical options.
Clarisse 810554 runs close to true to size for most customers, but because it is a fitted mermaid cut, the fit through the hips and thighs is where the sizing decision matters most. Measure your bust, natural waist, and the fullest part of your hips, then compare those measurements to the Clarisse size chart rather than relying on your usual dress size.
For fitted mermaid silhouettes, the general recommendation is to size to whichever measurement is largest on the size chart. If your hip measurement puts you in a size 8 but your bust puts you in a size 6, order the size 8 and have the bodice adjusted by a tailor if needed. Taking in the upper body is a simpler alteration than trying to accommodate hips in a gown that is cut too small.
The Clarisse 810554 is available in extended sizing — sizes 16 and up are offered, and the proportions in those sizes are drafted accordingly. If you are shopping in the extended size range, the same measurement-first approach applies. When in doubt between two sizes in an extended range, size up.
For height, the sweep train means the gown is cut for a standard formal dress height with heels. Petite wearers may want to have the hem and train adjusted by a tailor to prevent excessive drag. This is a straightforward hem alteration on a lace gown and most tailors can complete it in one appointment.
Yes, and it works well for group coordination in a couple of different ways. The two colorways — Pale Lilac and Black — are distinct enough that a court or group can split across them without the looks clashing. A common approach is to have the lead wearer in one colorway and court members in the other, or to let each person choose the colorway that suits them best within the same style.
Because the 810554 shares the same silhouette, neckline, and silhouette across both colorways, photographs of the full group will have a cohesive look even when the colors differ. The fitted mermaid line reads consistently across body types and sizing, which helps the group look intentional rather than mismatched.
If the full group is ordering, it is worth placing all orders at the same time so Marlas Fashions can confirm stock availability across sizes and colorways before any one person's order is processed. For groups of three or more, contact the team in advance — the team can often confirm availability for the full size run before you commit. Text or WhatsApp the Marlas Fashions concierge at +1 416-536-2956 or +1 213-868-3131 to coordinate a group order.
