Young Brunette Girl Undresses Her White Chemise And French High-cut Briefs At Home

In the United States, a slang term for briefs is "tighty-whiteys" (with various spellings and inversions: "tidy-whities", "whitie-tighties", etc.). The exact origin of the term is unknown, but it has often been used as an epithet.
In recent years, a hybrid called boxer briefs has become popular. Like boxers, they have short legs, but like briefs, they are made of elastic, snug-fitting material. A shorter version of boxer briefs are called trunks.
