This is a thin knit vest. I bought it at Birthday last year!! I've only worn it for one season, and it's a little bit pilled. Also, the buttons are a little loose, but I think it can be worn without any problems ⭐️ (See the third photo) It's a Korean-style vest that you can wear fashionably ✨ - Color: Beige - Design: Geometric pattern - Material: Knit - Buttons: 4 buttons - Style: Cardigan style Thank you for looking.
