If you missed my outfit ideas for round one you can read it here.
Round two is generally the most casual day of rush week. Most schools will have you wear a rush week t-shirt and tell you to wear casual shorts with flat shoes.
When picking out shorts make sure the length is appropriate. I would try to stay away from plain khakis or boring shorts since you want to stand out. Also, don’t forget that a lot of dressier shorts have bows and ruffles that might not look right with t-shirts.
