Description
About the Dress: Sherri Hill 57785
Sherri Hill 57785 is a strapless mermaid trumpet gown in an all-over floral pattern on an ivory ground, available in Lilac, Light Blue, Pink, and Ivory. The structured bodice sits flat across the chest with a subtle center dip at the neckline, and the silhouette fits close through the hips before opening dramatically into a sweeping train. This is a bold, statement dress built around one central idea: let the fabric and the shape do the talking.
Fit & Silhouette
Sherri Hill 57785 follows a true mermaid trumpet cut — the skirt hugs close through the thighs and flares out below the knee into a full sweep with no slit. The bodice is fitted and structured, designed to sit snugly from chest to hip. Because the skirt is fitted through the thighs, movement is intentionally controlled; this dress is made to stand and be seen rather than move freely. The open back drops from the top of the bodice all the way to the hip, so there is very little fabric behind you. Customers between sizes typically size up and tailor down for the best result through the bodice.
Fabric & Detail
The fabric on Sherri Hill 57785 is a structured woven with an all-over floral design — the pattern appears to be built into the weave itself, producing a dimensional texture across the entire gown. The raised floral surface gives the dress its visual depth without any additional embellishment applied on top. Visible boning channels run through the interior of the bodice, providing the lift and hold the strapless silhouette requires. The skirt extends into a sweep train that trails cleanly behind the flare. There are no straps, no sleeves, and no cutouts — just the fabric structure and the silhouette.
Key Features
- Strapless sweetheart neckline with subtle center dip
- All-over woven floral pattern with dimensional texture
- Structured boning throughout the bodice for secure lift
- Fully open back from bodice top to hip
- Mermaid trumpet silhouette with sweep train
- No slit — clean flare from below the knee
- Available in Lilac, Light Blue, Pink, and Ivory
Style & Occasion
Sherri Hill 57785 is designed for high-impact formal occasions where the dress is the centerpiece. It is a natural fit for prom, pageant competition, black-tie galas, and formal evening events. The dramatic open back and sweep train make it a strong choice for any venue with a runway moment — a grand entrance, a stage, or a ballroom floor. The floral colorways read differently under event lighting: Lilac photographs soft and cool, Light Blue reads airy and fresh, Pink leans warm and romantic, and Ivory is the most neutral and classic. All four colorways work well for formal and evening wear. The fully open back and formal silhouette make it especially well suited to evening receptions and black-tie wedding-guest occasions. Style it simply — a clean updo, minimal jewelry, and a strappy heeled sandal let the dress lead.

Frequently Asked Questions
The back of Sherri Hill 57785 is fully open — it drops from the top of the bodice all the way down to the hip with no coverage behind you. Because the dress is strapless and backless, all the hold comes from the structured boning built into the bodice itself. There is no zipper exposed at the back; the closure is typically a concealed side or back zip that runs along one of the seams, and the boning channels keep the bodice rigid against your torso once the zip is fastened.
What this means practically: the fit through the bodice needs to be accurate before you put the dress on. You cannot loosen or tighten a boned strapless bodice after the fact the way you might adjust a lace-up corset back. The boning creates a fixed structure, so if the bodice is even slightly too large, it will gap and shift; if it is slightly too small, it will dig in and restrict breathing. This is the most important measurement to get right when ordering.
For the bodice, go by your true bust measurement first, then cross-check against your underbust and natural waist in Sherri Hill's size chart. If your bust and waist measurements land in different sizes, size to the bust and plan for a small alteration at the waist — a skilled seamstress can take in the side seams without disturbing the boning. If you are between sizes, the standard advice applies: size up and tailor down.
The skirt is a separate consideration. The mermaid trumpet cut fits close through the hips and thighs before flaring below the knee, so hip and upper-thigh measurements matter as much as the waist. Check all three — bust, waist, and hip — against the chart and order the size that accommodates the largest measurement, then alter where needed.
One more point on the open back: because so much of your back is exposed, there is nothing to anchor the dress to your lower back. Movement is intentionally limited by the fitted skirt. This is a dress built for standing, walking slowly, and being seen — not for dancing freely or sitting for extended periods. Plan your evening around that, and the fit will hold perfectly all night.
Sherri Hill 57785 is built for a specific kind of event: high-visibility, formal occasions where the dress is meant to make a statement the moment you walk in. Here is a straightforward breakdown of where it works and where it does not.
Prom is the primary occasion this gown is designed for. The sweep train, the open back, the structured bodice, and the dramatic mermaid trumpet silhouette are all signatures of a high-end prom gown. If your school's prom is held in a hotel ballroom or large venue, this dress is entirely at home there.
Pageant is the other natural fit. The all-over floral texture, the fully open back, and the formal sweep train check the boxes for evening gown competition at the regional and state level. The silhouette photographs cleanly on stage.
Formal black-tie events and galas are also appropriate. If you are attending a charity gala, an awards dinner, a formal fundraiser, or any event with a black-tie or formal dress code, this gown reads correctly for that setting.
Formal evening events broadly — think film premieres, formal anniversary parties, or high-end corporate galas — work well.
As a wedding guest, this dress suits evening and black-tie receptions best, where its open back and formal silhouette are fully at home. The fully open back and dramatic silhouette are best suited to events where bold formalwear is expected, such as galas or black-tie evenings, rather than the more understated look typically appropriate for a wedding guest. Even at a black-tie wedding, a gown this dramatic can risk upstaging the couple, so pairing it with a wrap or shawl is worth considering if you're attending as a guest.
Cocktail parties, semi-formal events, homecoming, and casual formals are also not the right setting. This gown requires a proper formal venue with space for a train — a smaller venue or a casual setting will make the dress feel out of place.
In short: if the event has a stage, a runway moment, or a grand ballroom, Sherri Hill 57785 belongs there. If the event is anything less formal, choose a different style from the collection.
Sherri Hill sizing runs close to true-to-size for most customers, but this particular gown requires careful attention to three measurements: bust, waist, and hip. Because the mermaid trumpet skirt fits close through the thighs, your hip and upper-thigh measurements matter as much as your waist.
Use a soft tape measure and measure over bare skin or lightweight undergarments. Write down your full bust, natural waist (narrowest point), and full hip (widest point across the seat and upper thighs). Compare all three against Sherri Hill's official size chart, and order the size that fits your largest measurement. Plan a standard alteration for the other areas — a skilled seamstress can take in the side seams without disturbing the boning structure.
If you are between sizes, size up. The bodice has fixed boning channels; there is no adjustable lace-up closure on this style. A boned bodice that is too small cannot be let out, but one that is slightly too large can be taken in relatively easily.
Bring your actual measurements when you visit a bridal or formalwear alteration specialist, and allow time before your event — complex alterations on a structured mermaid gown can take two to four fittings.
The bodice of Sherri Hill 57785 has structural boning throughout, which provides lift and hold on its own for most customers. For many wearers, no additional undergarment is needed under the bodice — the boning does the job a traditional strapless bra would normally do.
That said, if you prefer extra security or want a smoother look through the hip and thigh, a few options work well. A low-back adhesive bra or silicone bra cups can sit inside the bodice without any straps showing. Seamless or laser-cut underwear in a neutral shade works under the fitted skirt without showing lines. Shapewear is an option but choose a low-back or backless style — anything with a full back panel will show given how low the open back drops.
Avoid regular strapless bras that sit higher on the back, as the open back on this gown drops to the hip and any bra band across the back will be fully visible. Stick to adhesive or built-in solutions only.
Yes, this gown can be hemmed, but a mermaid trumpet style with a sweep train is one of the more involved hemming jobs in formalwear. The flare and the train both need to be adjusted proportionally, and the hem of a structured woven fabric like this one requires a professional.
For petite customers, the goal is to maintain the flare point at the right position — if the hem is taken up too aggressively, the flare can shift from below the knee to at the knee, which changes the silhouette significantly. Discuss this specifically with your seamstress before any cuts are made.
Bring your shoes to your fitting. The height of your heel changes where the train sits and how much needs to come off the hem. Most alterations specialists will pin the hem with your shoes on to get the length right. Plan for at least one fitting before the final hem is cut, and ideally two if the adjustment is significant. Budget both time and cost accordingly — train hemming is not a quick fix.
The four colorways — Lilac, Light Blue, Pink, and Ivory — all share the same cream or ivory ground fabric with the floral woven pattern. The color sits in the floral design itself rather than in a solid background, which means the overall effect is softer and more tonal in person than saturated color photos might suggest.
Lilac reads as a cool, soft purple with a slightly muted lavender quality under warm indoor lighting. Light Blue is the airiest of the four — it photographs very softly and reads fresh and clean in person. Pink leans warm and romantic, closer to blush than hot pink. Ivory is the most neutral and classic, letting the woven texture carry the visual interest without any color competing.
For formal events under ballroom or stage lighting, all four colorways hold well. Lilac and Light Blue tend to read slightly cooler under white stage lights, while Pink and Ivory warm up. If you are choosing for a pageant where stage lighting is a factor, it is worth asking your director or stylist how your venue's lighting behaves.
Only Lilac is available in photographed samples — if you are deciding between the other three colorways, contact our team and we can help you compare.
After wearing, hang the gown on a padded hanger — never a wire hanger — inside a breathable garment bag. The structured woven fabric and boning channels need airflow to avoid moisture buildup. Store in a cool, dry space away from direct light.
For cleaning, follow Sherri Hill's care label exactly. A structured woven gown with interior boning should be professionally dry cleaned rather than hand washed. Spot-treat small marks promptly with a dry clean solvent cloth rather than water.
For travel, fold the skirt loosely with tissue paper between layers to prevent sharp creases in the woven fabric. The boning in the bodice means the top of the gown cannot be compressed — pack it in a garment bag laid flat in a suitcase or a proper gown travel bag, not folded tightly. If you are flying, check the gown in a hard-sided garment bag or carry it on if the airline allows.
Steam works well to remove travel wrinkles from the skirt. Do not iron directly on the fabric — use a pressing cloth and low heat if a steamer is not available, and keep the iron away from any areas with raised floral texture.
The all-over floral pattern and the dramatic silhouette mean the dress is already doing a great deal of visual work. The strongest styling approach is to keep accessories minimal and let the gown lead.
For shoes, a strappy heeled sandal in metallic silver, gold, or a neutral that matches your colorway is the cleanest choice. A closed-toe stiletto also works. Because the mermaid skirt covers most of your shoe, comfort and heel height matter more than the shoe's design — choose a heel you can stand and walk in confidently for several hours.
For jewelry, less is more. A simple pair of drop earrings or small studs reads well with the strapless neckline. If you wear a necklace, keep it short and fine — the bare collarbone and chest area is part of the look, and a heavy statement necklace will compete with the floral texture across the bodice. A delicate bracelet or a clean ring is enough for the wrist and hands.
For hair, an updo — a sleek chignon, a soft twist, or a high bun — works especially well with the open back. The exposed back is a feature of the gown, and pinning your hair up frames it properly.
