How should I dress for an interview for a volunteer position with my university's sexual education center? I'm know the actual job itself would require only super casual dress, but I want to make sure I look like I'm serious about the job and well put together. Also, it's stinkin' hot and I know the office where they preform the interviews is sauna-like. Help!

Considering the heat and the need for professionalism-meets-sexiness, I’d go for a nice dress if I were in your shoes. A non-black dress that makes you feel cute and smart. Maybe the kind of thing you’d wear on a first date to a poetry reading.
