Here is an awesome short sleeve t-shirt by Gap. 100% cotton and made in the USA. White shirt with adorable floral design on the front. This shirt screams 90's in the best way possible. Super soft and comfy, and in incredible shape with tons of life left. The tag says Small, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 16"
Shoulder to end of sleeve (including cuff) 4"
Length 19"

This item is sold from a vintage boutique in Roanoke, VA.
