I rushed through formal recruitment so I never had the dilemma you're having because we got "suggestions" for outfits each day. But as a sister, I noticed what the girls who came through informal recruitment wore last spring. I'd definitely say no jeans. For the first day, I'd go with black pants and a nice shirt or sweater (you said it's cold- you can always wear a heavy jacket and take it off when you get there). Most of the girls who came through our informal rush wore black pants or other dressy pants and a few even wore a lowkey dress on the last night. It's always better to be overdressed than underdressed. The sisters may not take you seriously if you show up in something you might wear to class. And you can always look at how the sisters are other PNMs are dressing to get an accurate idea of what to wear. Good luck!
