I went to Navy Pier yesterday for a eighth grade class trip. when me and my friend were walking around a shop with one whole wall was filled with hats of college and professional sport teams that all had logos that lit up. so me and my friend went inside and saw you can make your own custom made hats. with flat brims and normal caps in all colors and the abiltiy to out lettering on the hats in any color, there were probally millions or more options to customize your hat. i got a black flat brim hat that i but custom letting on in one of ten styles of script that you can choose from. each at cost $20 and you get 7 free letters with that (Spaces dont count as letters) and then each extra letter is .50 cents. you can get lettering on the back or front of the hat. so really there are trillons of combos you can make to personalize your own hats. the man was a younger guy who was really nice and was willing to help you out. my hat looks awesome and im actully wearing it right now! in the shop there are also a ton of hats that girls would like and a lot of silly/funny hats. i recommend DC Mad Hatter because it has good service, good quality, and great hats. next time you are at navy pier stop by DC Mad Hatter for sure.
