Description
About the Dress: Clarisse 810475
Clarisse 810475 is a long lace mermaid gown built for prom. The sweetheart neckline frames the neckline cleanly, spaghetti straps run from the front up and over the shoulders, then cross at the upper back in a crisscross pattern. The entire back from the shoulder blades down to the lower back is open. A swept train finishes the hem.
The lace covers the full dress from bodice to train — it is the primary and only outer fabric layer. Floral-pattern appliqué relief runs throughout the lace, and scattered rhinestone beading sits across the bodice for additional sparkle. Clarisse 810475 is available in Hot Pink and Royal Blue.
Fit & Silhouette
Clarisse 810475 follows a true mermaid silhouette. The fit is close through the bust, waist, and hips all the way down to the knee. Below the knee the skirt flares out and flows into the train. There is no slit. The dress is designed to be worn with minimal undergarments given the fully open back, and the sweetheart bodice is structured to provide front support.
Order your standard size. Lace has very limited stretch, so if you are between sizes, sizing up and having the dress taken in by a tailor is the safer choice. The crisscross back straps are fixed, not adjustable.
Fabric & Detail
The outer layer of Clarisse 810475 is lace from top to train. The lace carries a floral-pattern relief — the appliqué work gives the surface a three-dimensional texture that photographs well under both natural and stage lighting. Rhinestone beading is concentrated on the bodice, adding light-catching sparkle without covering the full dress.
The train is a soft sweep, enough to trail gracefully on the dance floor without being difficult to manage during the evening.
Key Features
- Long lace mermaid silhouette with swept train
- Sweetheart neckline with spaghetti straps
- Crisscross back strap construction
- Fully open back from shoulder level to lower back
- Floral lace appliqué relief throughout
- Scattered rhinestone bodice beading
- Available in Hot Pink and Royal Blue
Style & Occasion
Clarisse 810475 is a prom dress first and foremost. The open back, body-hugging mermaid cut, and statement train are built for a prom entrance. It works equally well for formal dances where a dramatic silhouette is the goal.
Hot Pink photographs with strong color under venue lighting — it holds its vibrancy on camera. Royal Blue reads deeper and richer in person than in some monitor displays; both colorways show the lace texture and rhinestone detail clearly.
For shoes, a strappy heel in a neutral or matching metallic keeps the open back and lace as the focal point. Keep jewelry minimal — small stud earrings or a delicate bracelet let the dress speak. A small clutch in gold or silver completes the look without competing with the lace and beading.

Frequently Asked Questions
Clarisse 810475 runs true to standard US sizing, but because the lace fabric has very little give, fit precision matters more here than it does in a dress made from stretch jersey or chiffon. The mermaid silhouette is fitted closely through the bust, waist, and hips all the way to the knee, which means even a half-size discrepancy can feel restrictive when you try to walk or sit.
Start by taking three measurements: full bust (across the fullest part), natural waist (the narrowest point), and high hip (about 7 inches below the waist). Compare all three against Clarisse's size chart — do not rely on just one measurement. The dress is graded to fit proportionally, and if your measurements fall in different sizes (for example a size 4 bust and a size 6 hip), choose the larger size and have the dress tailored in at the points where it is loose. Letting out lace is difficult; taking in is straightforward for any experienced formal-wear tailor.
If you are between sizes, size up. This is the standard guidance for any close-fitting lace gown, and it applies here. A size 8 that can be taken in at the waist will look and feel better than a size 6 that pulls across the hips.
For height: Clarisse 810475 has a swept train. The gown is designed for a height range of roughly 5'6" to 5'9" in a heel of 3 to 4 inches. If you are shorter, the train and hem will need to be shortened — this is a routine alteration. If you are taller, the gown may hit your frame more cleanly, but confirm the hem length when your dress arrives so you have time to schedule a fitting before the event.
For the bust area: the sweetheart neckline is structured with internal support, but because the back is fully open, you cannot wear a traditional bra. Backless adhesive bras or silicone cups are the standard solution for this style. If you rely on a bra for meaningful support, factor that into your size decision — having the bodice structured more snugly at the front can offset the lack of a bra strap.
Order early. Clarisse gowns ship from our Los Angeles and New York warehouses in 7–12 business days standard, with rush shipping available. For a prom date, ordering 6–8 weeks out gives you time for delivery and at least one fitting appointment without stress.
Clarisse 810475 is designed for prom. That is its strongest context, and every design decision — the open back, the body-fitted mermaid cut, the crisscross strap detail, the swept train — points toward a prom-night entrance. If you are shopping for prom, this is a dress that was built for that moment.
Beyond prom, it works for formal dances where a long, dramatic gown is appropriate — think winter formal, military ball equivalents at schools that allow open-back gowns, or a senior banquet with a formal dress code. The key question for any event outside of prom is whether the venue and the dress code accommodate a fully open back. This dress exposes the back from shoulder level all the way down to the lower back. In settings where that level of exposure is welcome, the dress fits. In conservative or religious settings, it does not.
For weddings, the fully open back is best suited to evening or black-tie receptions rather than daytime or more traditional ceremonies. The fully open back is something to keep in mind when dressing for a wedding; for more traditional or daytime ceremonies, a covered or minimally open-back style may be the more fitting choice. If you are a guest at a wedding with a black-tie or formal dress code, you would want to choose a covered or minimally open-back option instead.
For galas and evening events: the open back similarly limits its versatility. In a gala context where the dress code is very formal and the expectation is a conservative silhouette, this dress may stand out for the wrong reasons. In a younger, fashion-forward gala or charity event, it could work well — use your judgment about the audience.
For photos and pageant-adjacent settings: the Hot Pink and Royal Blue colorways both photograph with strong contrast, and the lace texture with rhinestone beading catches venue lighting very effectively. If you are attending an event where you will be on a stage or photographed under event lighting, both colorways will show well.
The honest answer: if the event is prom or a school formal, this dress is purpose-built for it. If the event is anything else, consider whether an open back fits the setting before ordering.
The back of Clarisse 810475 is fully open from shoulder level to the lower back, which means a traditional bra is not an option. The sweetheart bodice is structured with internal boning and a built-in cup, which provides front support without a bra strap.
For most wearers, a backless adhesive bra or a pair of silicone stick-on cups is the right solution. These are available at lingerie stores and most department stores in a range of sizes. Look for a style with a centre-front closure so you can adjust the lift — this works best with sweetheart necklines. If you need more support than adhesive cups can provide, talk to a tailor about having the bodice taken in slightly at the front to increase structure.
For the lower half: seamless, low-rise underwear or body-shaping shorts that sit below the hip are the standard choice with a mermaid gown. Avoid anything that creates a visible line at the hip, since the lace fits closely through that section of the dress.
Shapewear is optional. If you choose it, make sure it ends below the knee so it does not restrict the flare of the skirt when you walk. A thigh-length or knee-length shaping layer under a mermaid silhouette can cause the skirt to bunch or pull when you step.
Yes, Clarisse 810475 can be altered, and hemming is the most common adjustment for this style. The dress is designed with a swept train at the standard sample length. If you are shorter than approximately 5'6" in your prom heels, the hem and train will likely need to be shortened.
When you bring the dress to a tailor, wear the exact shoes you plan to wear on the night. The hem length on a mermaid gown is measured with the heel in place — alterations done in flat shoes will be off when you add the heel. Have the tailor mark the hem while you stand naturally, not on your toes.
For lace hemming specifically: a tailor experienced with formal wear and lace will know how to finish the hem without fraying or distorting the lace pattern. Ask about their experience with lace gowns before you book. A good finish on lace takes more time than on jersey or chiffon, so factor that into your timeline.
Other common alterations on this style: taking in the waist, adjusting the bustline, or tightening the back strap tension. All are doable by a skilled tailor. Allow at least two to three weeks before your event for alterations — one week for the work, one fitting appointment to check it, and buffer time for any adjustments.
The mermaid silhouette is form-fitted through the hips, which means movement is more restricted compared to a ballgown or an a-line. You will take smaller steps, and sitting down and standing up takes a little more care. That said, most wearers find they adapt within the first hour of wearing it.
For dancing: slow dancing is comfortable in this silhouette. High-energy dancing with big leg movements will be restricted by the fitted skirt. The flare below the knee gives you some room, but if you plan to be on the dance floor all night doing active dancing, keep that in mind.
The lace fabric is not particularly stretchy, so the dress does not give with your body the way a stretch jersey gown would. Wearing it in for a short period before the event — walking around your house for 20 to 30 minutes — helps you get used to the fit and confirms everything is comfortable before the night.
The train is a soft sweep, not a cathedral length, so managing it on a dance floor is straightforward. Most wearers learn to nudge it aside with a foot or let partners step around it naturally.
Hot Pink in person is a true, vivid pink — saturated and bright. It photographs well under venue lighting and does not wash out under stage or event lights. If you want to stand out in a crowd, Hot Pink delivers that.
Royal Blue reads deeper and richer in person than it sometimes appears on screen. Monitor calibration varies, so you may see it anywhere from a medium blue to a deep cobalt depending on your display. In person it is a true royal blue — not navy, not electric. The lace texture and rhinestone beading show clearly in both colorways, but the beading catches light differently: against the Royal Blue, the stones read as silver and cool; against the Hot Pink, they read slightly warmer.
Choosing between them comes down to your personal colour preference and skin tone. Both colorways are equally available and ship from the same stock. If you are uncertain, our team can help you think through which works better for your colouring and the lighting at your specific venue — text or WhatsApp us and we will give you a straight answer.
After wearing Clarisse 810475, hang it on a padded hanger immediately — do not fold or ball it up, as lace can crease and the appliqué work can snag if compressed. If the dress has any light surface marks, a lint roller removes most surface debris without touching the lace.
For cleaning: dry cleaning is the recommended method for lace formal gowns. Tell your dry cleaner that the dress is lace with rhinestone beading and floral appliqués — this helps them choose the right solvent and method so the stones and appliqué are not damaged in the process.
For storage between events: use a breathable garment bag, not a plastic dry-cleaning bag. Plastic traps moisture and can yellow lace over time. Store it hanging in a cool, dry space away from direct sunlight.
For travel: lay the dress flat in a large suitcase if possible, or fold it once loosely and lay it on top of other items rather than underneath them. A dry-cleaning bag or a large fabric garment bag inside the suitcase helps protect the lace from snagging on zippers or other items.
For shoes: a strappy stiletto or block heel in a neutral — clear, nude, gold, or silver — keeps the focus on the dress. The open back and lace are the statement; the shoes do not need to compete. If you want to match the colorway, a metallic in a warm gold works well with Hot Pink, and a cool silver or gunmetal pairs naturally with Royal Blue. Heel height of 3 to 4 inches is the typical range for this dress length.
For jewelry: keep it minimal. The lace texture, floral appliqué, and bodice beading already give the dress significant visual detail. Small stud earrings or short drop earrings in crystal or the metallic of your shoe are enough. A delicate bracelet or a ring is fine. A statement necklace will compete with the sweetheart neckline and the lace — skip it.
For a bag: a small clutch in gold, silver, or a colour that echoes your shoe. Keep it slim and simple — the dress is the focal point of the look. Call or text our Toronto boutique at 416-536-2956 and our stylists will help you find your perfect dress.
