The fastest and most effective way is: you may improve your hat by washing it with water.

Because the hat is made of 100% cotton, and the characteristic of 100% cotton is that it is first used in water. It will shrink when it is produced.

However, when the manufacturer produces it, the cotton cloth is not shrunk.

Why can’t the purchased hat be modified?

The reason is: Although the hat is small, each part of the hat is specific according to the curve of the head.

1) The top of the hat has a curvature and must be trimmed at the same time. You cannot modify any piece at will, otherwise the hat will be deformed

2) There is a button on the top of the baseball cap, which requires a professional button mold to put it on. There are no repair shops.

3) It only takes a few minutes to make a hat, but it takes a long time to modify a hat, and the modification may not be satisfactory.

Manufacturers have special molds.

If you want to modify it, every part needs to be modified at the same time, which is difficult for the master who repairs clothes.
