This is a Korean outfit I received as a gift. I think the size is around 80-90. I did a quick search online and screenshotted the size information from other products. It's made of a gauze-like fabric, which is comfortable to wear, and the check pattern is also cute. Please check the condition in the photos. Beige check long-sleeved shirt, size M. - Brand: Aosta - Size: M - Design: Check pattern - Sleeve Style: Long sleeve - Color: Beige Thank you for looking.
