I took this out during the seasonal change and it was too small. It's thin but made of a comfortable material that isn't see-through. Since it's used, please refrain from purchasing if you are sensitive to such things. I am also selling this on other sites, so there is a chance I may have to cancel the transaction due to timing. Please forgive me if it sells out. Simple and stylish black long-sleeved shirt, size M. - Brand: UNIQLO - Size: M - Color: Black - Design: Long-sleeved shirt - Condition: Like new Thank you for looking.
