This is a navy cocoon blouse, a popular item from soeju. I purchased it several years ago, before the design was changed. It's labeled as size S, but I believe it's equivalent to a current size M. It was convenient for subtly covering my upper arms. I mainly use other colors, and I've worn this one about 5 times. Please understand that it has been stored at home. Measurements (approximate): Width: 61 cm, Length: 54 cm - Color: Navy - Size: S (equivalent to current M size) - Design: Crew neck, drop shoulder - Style: Casual, simple Thank you for looking.
