After Halloween I purchased 3 t-shirts for 70% off the origional price which made for a great deal for me. The problem was that they all shrunk in the wash to sizes I can't imagine many people could have fit into. One of them I couldn't even begin to fit over my head. Luckily there are methods of stretching one's t-shirt to a better fit.
1
Start by cutting the collar away from the back of the t-shirt.
2
Cut the collar away from the front as far down as you want to go without actually removing the collar.
3
Clean up the collar then lay your shirt so the top side seams meet.
4
Cut out a pie wedge shape so that your shirt becomes off-the shoulder.
Stretch the shirt so it curls and you're done!
