Battling the heat through inappropriate attire

I think the heat is going to people's heads. Seriously, it seems to be affecting people's fashion sense. Walking to work this morning, I saw not one but two women wearing skirts so thin and light-weight that I could see their undies through them. I'm all for beating the heat through summer-weight clothes but not at the cost of flashing the entire Upper West Side. On the other extreme, I also saw a woman wearing pantyhose under her skirt. Her brain must have really been fried when she was getting dressed this morning.
