If you’re wearing a beret for fashion, there is really no limit to how it may be worn (as long as it’s sitting on top of your head). The most popular casual method of wearing a beret is to wear it without a fold and tilted so that the brim sits diagonally across your forehead. Usually casual berets need no shaping other than fuzz removal. [1] X Research source

Excess material will be folded and draped towards the right side of your head. This is typically why a beret must be shaped, as it will most likely resist holding this shape when brand new. [3] X Research source

Use a disposable razor. This is the easiest and most common method. Gently run the razor in a single direction over your beret. Make sure not to go over the same spot multiple times, as you risk wearing down the material too much. Carefully clip with scissors. This method is best if there are only a handful of obvious pills. Clip them off at the base, placing the scissors flush with the beret. Use cuticle scissors for the most precise control possible. Burn off the fuzz with a lighter. Hold the lighter in place and carefully run your beret just over the flame without touching it. Instead of “shaving” the entire cap, go over just the areas with visible fuzz. Although this method can damage your beret if done improperly, it is sometimes considered to be the traditional way to de-pill a military beret. Exercise caution when using a lighter.

Note: Using hot water on the black rim will shrink the beret. If your beret is slightly too large, using hot water is a good idea. If your beret already fits your head snugly, be sure to avoid hot water.
