First, I have used the search function and read the few posts about this question (including the one that was derailed by a discussion about whether women prefer cut men (a la Brad Pitt) or big men (a la the Rock)...). But they were all from 2010, so I was just wondering if anyone had any other thoughts given recent developments in the fashion world

I am going to be visiting my #1 school. I turned in my application in November and have not heard back yet. I emailed them an update (new grades, job stuff, etc.) a few days ago. I will be participating in a campus tour and sitting in on a few classes. So...
What do I wear?
2/3 of my older family members want me in a pantsuit. I think this is overkill (especially since my pants are all hemmed for high heel height. If I wear something else I can at least walk to the campus in flats). I would rather wear a skirt (probably tweed-looking), with gray ribbed tights, a sweater (pink or red), a button up shirt, and black pumps that I can walk in. Alternatively, I have a pretty cool burgundy button-up blouse that I could wear with said outfit.
Weather-wise, it has been raining/snowing recently there but it should be only "slightly cloudy" and around 40 the day I visit. I'm from a much more moderate climate, but I can usually survive with tights, a coat, and a scarf when it's around that temperature.
Thoughts?
Thanks!
