It's a slightly thin sweater. There were no size tags or anything from the beginning, but I think it can be worn by slender men, not just women. The sleeves and body have stripes, giving it a cool look. Please see the photos for the size. It's a knit, so it has some stretch, but the sleeves are slim. I would like to use recycled packaging for shipping. Immediate purchase is OK. #Slim fit sweater #Thin sweater
