F5 didn't work for me either, but F6 did! Sadly, once you rotate through the clothes, you're stuck with the last one (so stick with what you like, or you'll have a Master Scientist with a wife-beater and what looks kind of like a kilt!)
I'm feeling really behind, becauase I only have 9 villagers - I didn't get cracking on the "Breeding" (ugh.) quickly enough. Most of my villagers are now in their 50's! eek.
