First round: business casual. We have a very short recruitment period with only 4 chapters on campus, so first impressions are extremely important!
Second round: business casual. This is the first night PNMs see the chapter houses and take house tours. It is typically an evening centered around philanthropy and chapter-specific information. Our campus has less than 10% Greek involvement, so most PNMs know very little about Greek life in general. The first round is spent answering those typical questions.
Day 3: Preference ceremony/formal teas. This is cocktail attire. My chapter (as I'm sure others do) prefers PNMs to arrive in cocktail attire that is classy and elegant but shows a bit of her own personality and a splash of fun color.
These are definitely some samples of what I would wear if I could do it all over again! Dressing up for recruitment was so much fun.
