This shirt features a design with lightweight polyester material and five-分 sleeves. I purchased it last year, but I'm selling it now because it's been sitting unworn for about a year. It has been worn a few times, so I would appreciate it if those who understand used clothing would consider purchasing it ◟̆◞̆ The sleeves are puffy and very cute! I wore it with thin turtlenecks in the cold season, so I think you can wear it for a long time! - Brand: URBAN RESEARCH - Material: 100% polyester (outer), 100% polyester (lining) - Style: Five-分 sleeves / Three-quarter sleeves - Size: Free Thank you for looking.
