[Ghoulish Delight]

I know this sounds counter intuitive with the heat, and not having been in Florida-level humidity in quite some time I might be wrong - but layering with cotton under shirts is a good way to go. As long ad you're sticking with short sleeves, a cotton undershirt with a light weight button down on top, looks great, and keeps the perspiration out of sight. I favor a solid color under shirt with a casual patterned linen (or faux linen) on top. And you can't go wrong with jeans (but then long pants in heat never really bother me, ymmv). Gap makes the most comfortable, best fitting jeans I've ever owned (the classic 1955s), worth the cost.
