I got a band shirt from one of my friends, but it was men's L size. Even women's XS is sometimes too big for me (it's unbelievably hard to find suitable clothes), so I had to be a bit creative, because I didn't really want to stuck it somewhere in the closet and forget it there, because it's actually quite valuable... And I like the radioactive sign in the sleeve.
So, I took in quite a lot from the sides and made it slimmer also in the back plus added some holes for a ribbon. Cute. :) (I should move during this month and my room looks like a pigsty, so you have to be happy with an empty corner as a background.)
