i started out wearing a skirt, but it's just so damn uncomfortable to wear hose, and sometimes it's really cold. so i've been wearing pants lately. it's interesting that on ophtho interviews most women are wearing pants, but on prelim medicine most wear skirts. i just figured i'd switch it up depending on how i was feeling that day. i don't think it matters much- as long as you look nice, i'd say wear what you're more comfortable in.
