Hi everyone! I've been a silent lurker on GC for a while, and just today I decided to ask a few questions about outfits! Though I know outfits differ from school to school, but I want to keep my location anonymous. The only thing I will say, however, is my schools suggestions for outfits are pretty much the same as every other school with a large greek life! (Sorry for the vague description

)
Anywhoo, I've been putting some outfits together. Some of my clothing I could not find on polyvore, so I'll just give an overal description.
For Day 1 (House Tours): I was planning on wearing this dress

(I'd just like to add that the dress is not as baggy as it appears, but it's the only picture I could find)
Day 2+3 (Philanthropy night): I don't have images of these, but both nights I was planning on wearing Lilly skirts and a coordinating top with flats.
Day 4 (Pref Night):

with wedges. I'm mostly concerned this isn't dressy enough.. any thoughts?
Oh, and I'm so sorry there are a billion other threads just like mine! And yes, I do rather like Lilly

So thanks so much for reading!
ETA: Thanks for all the help guys!
