S​igma Kappa has two formals each year: Pearl Premiere in Fall, and Crush Party in Spring.

When you're a Sigma Kappa, Fall = Pearl Premiere! Having just taken in a new member class by that time of year, initiated members and new members get to share this special night together. Every Panhellenic sorority has a Big & Little Sister program, but Sigma Kappa takes this connection to a whole new level. Every year at Pearl Premiere, Sigma Kappa hosts a special ceremony to reveal the new members' Big Sisters. The ceremony involves a unique reveal that always lands as a favorite memory to every Sigma Kappa.

"Its not love, it's not lust; settle down boys, it's just a Sigma Kappa Crush!"

Every Spring, the beautiful ladies of Sigma Kappa shine at their last formal of the year. This formal holds a different meaning to each sister. For the graduating Seniors, Crush Party is their last Sigma Kappa formal to dance the night away with their sisters. For the newest members, Crush Party is their first formal as an initiated member of Sigma Kappa.
