Whether you've lost a few pounds or you bought a top that was one size too big because the design was totally irresistible, it's possible to shrink some garments for a better fit. Cotton, denim and polyester are the best candidates for shrinkage, and it helps if the item has not been preshrunk. Usually the trick is to do the opposite of what the care label on the tag calls for. It's always a risk, though—in general you cannot control how much the item shrinks, so proceed with caution.
How to Shrink Clothes Easily
Wash the item in hot water. In the case of dark blue denim, add 1 cup of white vinegar to the cycle to prevent fading.
Run the item in the dryer on the highest setting. Check on the item in 15-minute intervals to see whether it has shrunk to the size you want. If not, continue the cycle. Alternatively, set the item out to dry in the hot sun.
Iron the item on a hot setting.
