It’s listed as a S/M, but since it’s a caftan, it is open to most sizes, the accompanying slip is a S/M which would stretch to fit up to an 8/10, but no larger than that. It is sheer, but the sequins make it not obscenely sheer. Measurements: Bust/Waist/Hips: Open to 90” Length: 38” I never wore it, so there is no sequin loss
