Boutique minidress strapless

Purchase this from a boutique in Philadelphia several years ago worn once for a graduation. Beautiful abstract detail of gray blue army green taupe black and white. Small back slit. Fully lined. Strapless with side zipper. Stretch on back for comfort and nonslip inside top for more support. Beautiful ruffle detail at bust. Size small. Looks like Anthropologie style. Tags: express. Lulus.
