I think Janice wore tuxedos at formal events because she's the kind of girl who wouldn't be caught dead in a dress. Think about it. She plays bass(?) in a band. Girls I've met or seen like that are just a bit more tom-boyish (okay, alot!) and would much prefer to wear pants. And I'm not sure, but I don't think girls pant outfits came into style until recently. Short skirts are a completely different matter, though.
