Diane von Furstenberg Jewel Wrap Dress Size S
The size tag is no longer there but this dress fits the mannequin well and it is a small. I wear a medium/large and it was snug on me.
From Website: "Inky black and a saturated grand-scale floral print lend the impression of separates to an endlessly chic incarnation of Diane von Furstenberg's iconic wrap dress, styled with three-quarter sleeves for season-spanning versatility."
