Hello and welcome back...
French knickers (also called tap pants in the United States (US)) are a type of women's underwear or lingerie.
The term is predominantly used in the United Kingdom (UK) and Australia to describe a style of underpant that is similar in look to a pair of shorts. French knickers are worn from the hip, concealing some of the upper thigh and all of the buttocks.
French knickers are not to be confused with other underpant styles like "hipsters", "briefs", "bikini bottoms" and "boyshorts", all of which feature elasticated leg openings and fit more snuggly to the body.
