Gaffs are special made panties for tucking. Tucking is a technique where one flattens their genitals to hide an unwanted bulge.
Tucking is a vital part of everyday well-being for many trans women and trans feminine people, but it can also be done by e.g. gender fluid and gender queer people, cross dressers and drag artists, or anyone who wants a flatter frontside sometimes or daily.
