TRI ESS

TRI ESS (SSS, Sigma-Sigma-Sigma, Society for the Second Self) is a US-based social and support organization intended primarily for heterosexual crossdressers and their partners.

History

TRI ESS was founded by Virginia Prince in 1975 as a continuation of FPE, an existing distributed support group. In 1976, TRI ESS absorbed Mamselle, a similar group. Also in 1976, Tri Ess rejected a proposal to merge with the International Alliance, a similar group which had broken away from FPE/Tri Ess within recent years.

The group remains very active today with several chapters and independent members throughout the US.
