The button on a baseball cap is difficult to fix because of it's size and the location on the top of the cap. However, a button may be removed and another one placed in the location. A hat-shop may be able to replace this button for a small fee.

The hat Brad is wearing in the photo is not a Newsboy Cap. Per my research, the Newsboy cap is usually 8 stitched panels with a button at the top. As you can see the cap pictured has neither. As it turns out, the cap is called an Ivy Cap. I found this exact cap as pictured at e4hats.com for 15.95 (a very good price) with high quality wool and it is imported. The cap with 8 stitched panels with a button at the top is a Baker boy.
