Beautiful and well made lightweight lamb leather wrap jacket from Theory. Can be worn alone or under heavier coats. The choice is yours. This piece is PREMIUM with a classic but modern design and will stand the test of time in your wardrobe. The wrap style wraps around and secures with a button inside and zips at the outside. I imagine it can be worn open as well. Please know your fit in theory It is a sz 0 and is fitted. Just gorgeous!!!
