ACEMI from Anthropologie mini dress cap sleeves heathered gray open back

Acemi from Anthropologie mini dress in heathered gray. Fit and flare and very comfortable. Great amount of stretch and I MUST say how soft this piece is! There’s a single bar across the open upper back and has round neck. No fabric content or size tag. Please see measurements for fit. My guess is S or XS based on measurements. Hand wash cold; flat to dry. 86% rayon 10% polyester 4% spandex. Approximate Measurements (laying flat): bust: 13” length: 33” pit to cuff: 1” (0704)
