Do you want to buy this old shirt of mine?
I "outgrew" it!
 
It was one of these:

I made these to complement my set design for "Stripe Tease" at the Walker Art Center in 2015.

I think it was a small but it has been washed.
I cut the sleeves and hem- it's a tank top now!
It's about 17" armpit to armpit when measured flat.
About 22" from the top of the shoulder to the curled up bottom hem.
An XS?
 
ROCK IT!
