When the weather is hot and humid, and you still want to look sharp and put together, there is no better fabric than linen. You're still wearing a button down shirt, but the breeze flows right though it. It has body, so it keeps a nice drape and rumples just enough to make it look like you don't try too hard. Wear it to dinner or throw it on over swim trunks to the beach -- no one will be better dressed for either occasion.
