New without tags, and the tags on the inside are not there either. I measured and she was fitting towards an XS. I’m normally an XS/S and I did fit into this so potentially a small could fit in as well but otherwise I would say true to size. She is stunning with the buttons down her back, and her love sleeve simplicity. Pair her with a belt or wear her as is. Either way she is stunning. •Shell: 95% Polyester, 5% Spandex.
