These are adorable. Lightweight searsucker material. Cinches in the back to be more fitted in the waist. No tags, believed to be a sample for UO or FP. Missing a button on one side as shown, could always take from the straps as there are two on each strap. No interior tag, so I tried on for you. I am 5’3” and ~115 lbs, typically wear an XS/S.
