I went through recruitment about 3 months ago.
This is for a school in Texas with a 5 day recruitment. I also really like Kendra Scott... sorry.
Intro Day
We were given a tshirt to wear and told to wear flats, cute modest shorts, and casual makeup and hair.
Philanthropy Day
Day 2 was seen as "going to tea with Grandma" or "going to church" kinds of outfits. Classy, modest, semi-casual, etc. Usually flats, some girls wore wedges.
Skit Day
Dresses usually, or skirts and a blazer. Interview wear. Wedges or heels are advised.
Pref
Fancy! Heels, cute fancy dresses, hair and make-up totally done up. We were told to make it a less sparkly homecoming dance outfit from high school.
Bid day
We were given a t-shirt from our sorority so we were told to wear a random tank top or undershirt that we could easily change out of. Converse, cute jean shorts, and casual hair/makeup were perfect.
