Twice a year, the chapter dresses to the nines to celebrate our Semiformal and Formal events. Every fall, we enjoy a night of dancing and festivities at a local San Luis Obispo venue. Then, come spring quarter, we make the trek out to Las Vegas to celebrate our annual Formal event. Spanning three days over a long weekend, Sigma Pi has over 120 brothers and dates in attendance. Our formals make for some of the most memorable and delightful nights of the year for brothers and dates alike!
