We don't buy new clothes, but we wear nice clothes. I usually wear nice tshirts or polo. I feel generally alot of people "dress up" to go to Disney. Its just a higher caliber park, and I think alot of people feel that the sleeveless Ron Jon Surf Shop shirt just isn't dressy enough. Granted there are the people who wear that stuff, but I'd say in a given day you'll see way more polos and nice shirts as opposed to the competition where you are lucky to see people with a shirt on at all!
