Sequin Mermaid Prom Gown with Cut Out Back

A sequin mermaid has less give than anything else on this page, and that single fact should drive your size choice. The Sequin Mermaid Prom Gown with Cut Out Back carries sequins, beads and embroidery over its base cloth, and a field of stitching that dense stops the base moving at all.

Where a Mermaid Fits Tightest

The narrowest point of a mermaid is not the waist. It is the thigh, somewhere between the hip and the knee, where the skirt is still following the body before it releases into the flare.

So the hip measurement decides this gown even though it comes last in the general sizing order. Check it against the table below before you check anything else, because a bodice that is slightly snug is a minor alteration and a skirt that will not close over the hip is a returned parcel.

Sitting and Walking in Sequins

The flare opens below the knee, which shortens your stride and turns stairs into a one-step-at-a-time exercise. Nobody mentions this and everybody discovers it on the night.

Sequins are also stitched facing one direction. Drawn against the grain they catch on stockings, on upholstery and on anyone standing too close, so sit down slowly and smooth the skirt downward rather than up.

Prom and Photographed Evenings

Champagne, green and rose gold under a flash are the reason this gown exists, and the illusion sweetheart neckline with a cut-out back gives a photographer two completely different pictures of the same dress.

It is the wrong buy for an evening spent dancing or a long seated dinner. The same density that holds the shape is what stops the skirt moving with you, and no amount of styling gets around it.

Sizing a Sequin Mermaid

Seven lettered bands are cut for this gown. Read the hip column first, which is the reverse of the usual order and correct for this one shape.

Every figure above is in inches and is taken on the body rather than on the finished garment, so measure the fullest part of the bust, the narrowest part of the waist an inch or two above the navel, and the fullest part of the hips.

Take the larger band wherever two look plausible. The general alteration limit is about two sizes down, and on a sequined gown that headroom is worth more than usual because the cloth itself contributes nothing. There is no stretch here to rescue a band that is fractionally short.

Alterations and Everyday Handling

Can a sequined gown be taken in? Yes, but it is slow, skilled work. Every sequin sitting over the seam has to come off by hand and go back on afterward, so the job costs more and takes longer than the same alteration on a plain gown. Book the fitting weeks ahead, not days.

Should I hem it for flat shoes? Better not to. The flare is part of the silhouette and shortening the skirt cuts into it, so the gown stops reading as a mermaid. Pick the heel height first and have the hem set to that.

Do sequins come loose? Individual ones can, usually where the gown rubs against a seat or a bag strap. They are stitched rather than glued, so a lost sequin is replaced with a needle and thread and does not run like a dropped stitch in a knit.

How should it be stored between wearings? Hanging, on a padded hanger, with nothing pressed against it. Sequined cloth folded in a box for a year comes out with the sequins crushed flat in the fold lines, and those do not lift back out.
