I'd recommend buying a hat with that little plastic adjustable bit in the back. That way the hat costs less, and you can still fit it perfectly to your head. If you want an even better fit, get one that uses velcro or one of those strap thingies that comes back on itself.
Oh, and take the sticker off. I saw the pictures in the photo thread. 👎
Seriously, who washes a hat?? You wear it until it's gross and then you buy a new hat.
Edit: The idea with the sticker is to prove that you've got enough money to buy a new hat on a regular basis. Now, stop for a moment and think about that. Having enough money to buy a hat on a regular basis = pimpin'? How lame is that? It's like if I were to leave the sticker on my shoe laces. "HEY EVERYONE! I have so much money I can buy new shoe laces every day!"
Edit2: Also, that's why you're having so much trouble figuring out how to clean this thing and keep the sticker on. The sticker is there to prove that it's so new it's never been cleaned. That's the whole point of the sticker!
