Since the black hats are still around, white thread was deemed the color that showed up and looked the best for all hat colors.
Hats come in adult, youth, and infant.
They are selling like mad and are flying off the shelves faster than can be stocked. However, there really is no danger of them running out. As someone whom works in the stockrooms, Disney has ordered ALOT of those hats.
I'm buying mine early but am not gonna wear them until we go back to the park 5/5. I'm surprising my best disney bud w/ a pair too. She'll be soo excited!!!! I'm not gonna give them to her until we are in the car and pulling into the park!!!
