what a great idea!
for 25 bucks you can buy a cool t-shirt designed by a cool band for a good cause - clap your hands say yeah, rilo kiley, stars, and wolfmother have all designed tees...and my favorite: joseph arthur.
all the profits go to the artists' chairty of choice.
sadly, no girl sized shirts at this time, but i emailed 'em to see if it was in the plans for the future.
EDIT: i got a response from the ybp people and this is what they have to say about girl shirts:
Hey Amber!
Thanks for your inquiry. Our t-shirts are unisex.. meaning, that
if you order a smaller size, it will fit perfectly. If you ordered an
xs, or a small, then i'm sure that it will fit properly. I hope this
helps!
