It's easy to make an adjustable baseball cap smaller by tightening or loosening its band at the back. Fitted baseball caps, however, come in fixed sizes. Fortunately, fitted caps can still be made smaller by shrinking the fabric of the hat's inner headband. This process is not difficult and will not damage the hat. Ideally, the wearer should go back to the retailer for an exchange to a smaller size. If that is not possible, or the wearer is in between two sizes, this method works well.
- Skill level:
Things you need
- Spray bottle
- Hair dryer
- Wig stand (optional)
Use a spray bottle to spray water along the inside rim of the hat, also known as the headband. Spray enough so that the band feels wet when you pinch it, but does not drip with water.
Leave the cap out in the sunshine or use a hair dryer to dry it. If possible, place the cap on a wig stand while drying, to ensure that it dries in the proper head-shaped form. Check the cap regularly by trying it on and making sure it is not shrinking too much. Once it is the proper size, wear it immediately or remove it from the heat source to avoid further shrinkage.
Repeat Steps 1 and 2 if the hat is still too large. Use more water and dry it with the hair dryer rather than sunlight. The hair dryer produces more direct heat than sunlight, so it is the better option for more extreme shrink jobs.
Tips and warnings
- Most fitted baseball caps are 100% wool; if not, this method may produce less effective results.
