One Size fits most. Very stretchy with no distortion of sequin graphics. Great for packing in your overnight bag or suitcase as this material is wrinkle resistant. Mannequin is a size 14 and there is plenty of stretch. My sis is a size 4 and it looks great on her too. Throw on a sheer duster or fur overpiece and you’re party ready. Or use as a comfy lounge piece. Polyester (95%) Spandex (5%) blend is both comfy and flattering. 562
