Beige short-sleeved crew neck sheer shirt. This is a sheer, short-sleeved shirt. Width under the armpits: 52cm Length from the top of the back collar: 51cm Please allow for some slight variations. The width under the armpits is quite wide, so I think it can be worn by someone who usually wears a size M. Because it's a sheer material, it's smooth and easy to wear, and it dries quickly when washed. #Uniqlo #UNIQLO Thank you for looking.
