The soft feel of cotton briefs make them a staple in most dresser drawers, but sometimes the fabric stretches, leaving you with sagging underwear. To shrink 100 percent cotton briefs requires using heat to reduce the material fabric. Hot water and the heat from a dryer will shrink 100 percent cotton while leaving the integrity of the fabric intact. Shrink your baggy briefs so they'll fit comfortably once again.

Separate the cotton brief underwear you want to shrink from the rest of your laundry.

Fill a sink with hot water. Dunk the underwear into the water and allow it to soak for 10 minutes.

Drain the sink and squeeze out the excess water. Place the underwear into the washer. Set the washer to hot water and a small load. Pour in 1 tbsp. liquid detergent. Wash and rinse the underwear in the hot water setting. After washing, remove the underwear and place it in the dryer.

Dry the underwear on the hottest temperature for the dryer. Inspect the underwear after 20 minutes. Continue drying for another five to 10 minutes if the fabric is still damp. Dry the underwear completely before placing them in your drawers.
