It's a navy, towel-like long-sleeved shirt. The neckline, hem, and cuffs were loose from the time of purchase. The neckline is particularly wide, so please look closely at the photos. I couldn't quite pull it off myself, so I wore it a few times, washed it, and kept it at home. I believe the size is around M. If you think you can style it, please take it! It's used, so please only purchase if you understand this!
