Bride fetish
From wipipedia.org

A bride fetish is a sexual fetish in which either a woman (or possibly a man) enjoys dressing in the typical outfit worn by a bride, or someone derives sexual pleasure from viewing women (or possibly men) dressed in this manner.
A bride may be regarded as the archetype of a virgin ready and waiting to have sexual intercourse. Brides often wear lingerie such as basques or corsets, stockings and thongs; they also wear stiletto shoes. For a transvestite, it may be the ultimate female apparel.
