This is a Nico and... all-in-one. The design is stylish and cute, it's wrinkle-resistant, and it's washable at home♪ I've worn it to small dinner parties and my child's graduation ceremony♪ It has a back zipper. I've worn it about 3 times, and there are no noticeable stains, but please understand that it's been stored at home by a non-professional, so there may be oversights and inaccuracies in the measurements m(_ _)m Size: M Length: Approximately 132cm Material: 100% Polyester Color: Black
