One size. Sheer deep purple fabric with gold and silver floral surface pattern.
If you’re on the short side, you may have to hem it as the length is best for a mid-height to tall person. Caftans are great beach or pool cover-ups. I also like the idea of cropping one to tunic or knee-length and belting it (gold metallic would look exceptional) over a silk camisole or slip with stockings or slacks and boots. Delicate wash.
