I also have to applaude people who walk around outside in suits, but look like they're walking along an air-conditioned building. I never look cool (literally and figuratively) during the summer. I get kinda sweaty, I look irritated, and while I LOVE hot weather, it's really difficult to wear things other than shorts, tank tops, and sandals.
I'm staring to wear more skirts and flowy trousers--anything that's as good as shorts without actually being shorts. I could also probably help myself out and wear lighter colours, but let's be realistic.
