Photo by Hector Mediavilla, in his show "Society of Tastemakers and Elegant People,'' at the Cantor Art Gallery, at the College of the Holy Cross, Worcester, through Dec. 15.. Spanish photographer Mediavilla's images capture the art form of Congolese men known as ''Sapeurs,'' who have used dress and performance to counter the realities of political and economic hardship in postcolonial Africa.
