How do i shrink a white shirt that is one size to big?
For the shirt, wash it on the highest possible temperature. Then, put it in the dryer at the highest possible temperature and then leave it in the dryer longer than you normally would. See www.ehow.com/how_4474618_shrink-shirt.html for details.
Wash it in hot water and tumble dry it!
wash and dry about three times on high ---
Well if it is made out of synthetic fabric like polyester, it will not shrink.
