Satin Corset Prom Dress Sweetheart Spaghetti Strap Long Evening Gown with Slit Lace‑Up Back for Bridesmaid Formal Occasion

It is a classic A-line gown: the corset bodice is fitted through the bust and waist with internal shaping seams, then the skirt flows out from the waist to the floor in soft, even folds. The A-line shape is one of the most universally flattering, because it defines the waist while the skirt skims over the hips and legs. The thigh-high front slit adds ease of walking, dancing and sitting, so the long skirt never feels restrictive.

The back is laced with satin cords through a corset closure, which lets you tighten or loosen the bodice for a flexible, personalized fit. It is especially useful if you are between sizes, since the lacing can adjust through the waist and back. Lace the gown to sit snug but comfortable, then finish with a bow. The corset lacing also creates a beautiful, structured finish from behind when you are walking or dancing.

The slit is a thigh-high cut designed to open at the upper thigh, which gives you a leg-lengthening line while keeping the overall look formal. It allows you to walk, climb steps, sit and dance without the satin pulling. Many guests wear this style comfortably at prom, weddings and military balls. If you prefer a little more coverage, you can also ask about custom length adjustments before ordering.

The gown is offered in standard US2–US16 and curve sizes 16W–26W. The heavy satin, full lining and adjustable lace-up back are designed to flatter both standard and plus-size figures. Please measure your bust, waist and hips in inches and compare them with our size chart before ordering. If your measurements fall between two sizes, the lace-up back gives you some flexibility to size up or down.

The gown is made in multiple solid colors, with the style shown in Emerald Green. The exact shades available at any time can vary, so please check the color selector on the product page for the current list. Solid colors are a timeless choice that works with bridesmaid palettes and formal dress codes, and the satin sheen looks rich across both dark and light shades.

Spot clean small marks or have the gown dry cleaned to protect the satin and the corset structure. Do not bleach, wring or tumble dry, as these can dull the sheen or alter the shape. If the satin creases, steam it or use a cool iron on the reverse side. Store the gown hanging rather than folded, and the skirt and bodice will keep their clean lines.

Production takes 3–5 business days. Standard shipping to most US states arrives in about 6–8 business days (8–10 calendar days), so total delivery is roughly 9–13 business days. Expedited shipping shortens the shipping window to 3–5 business days (5–7 calendar days). Free shipping applies to most continental US states; Hawaii, Alaska and Puerto Rico are excluded. Major holidays may cause slight delays, so we recommend ordering early for a prom or wedding date.

Standard-size gowns can be returned within 30 days after you receive your package. Items must be unwashed, stain-free, in original condition and with all clothing tags attached. We suggest trying the gown on as soon as it arrives so there is plenty of time for an exchange if needed. If you request a custom color or length, those pieces are made to order and may not be eligible for standard returns, so please confirm measurements with us beforehand.
