Here at FSU, we have wardrobe committee that selects 3 outfit choices for each day of recruitment. Then each sister (seniority counts here) picks which of the 3 she'd like to wear, and the numbers just happen to come out pretty evenly. For Pref, the sorotiy distributes fabric and a pattern #, and we have our dresses made. This year, they're scarlet iradescent- 1 shoulder, tube, or spaggetti strapped.
