This is a vintage waffle weave thermal shirt from the 1950s. I’ve never found a short sleeve one like this. Pretty cool! It’s a really nice staple!

Brand - Sears Roebuck and Co

Size - Labeled Medium but I think it’s better for a modern XS/S. It is on a women’s modern size 6 mannequin in the photos.

Chest - 15” pit to pit but stretches to 18”

Length - 25. 5”

Condition - I found a few light marks on the back
