A tri-sigma is a woman of class and stature. She is the girl next door. She is a little bit of everything; a trendsetter, an artist, and an athlete. She is classy, honest, chill, and respectable. She is the definition of sexy. A tri-sigma is who everyone wants to be. A tri-sigma girl is always on top.
