The average sequin dress is worn once, photographed, and never touched again. It scratches, it sheds, and it only suits one kind of evening. Ours was cut as a knit first and a sequin dress second — which is why it survives a wash, works with a cardigan at noon, and still holds a room at nine.
I have a wardrobe of sequin dresses I wore exactly once. This is the first one that made it into normal rotation.
