French Maid outfits, worn by women, are an occasional subject of sexual fetishism. They are a form of ladies' fantasywear that depending on design details can be classified as sexy lingerie. The name French maid derives from their being worn by stereotypical characters in risque burlesque dramas of the bedroom farce variety.

A wide variety of costumes are manufactured and marketed under the "French maid" description today. These range from comparatively modest dresses extending well down the thigh to transparent nightgowns or outright lingerie ensembles that cover almost nothing. Some sexy uniforms are marketed to transvestites.

The classic French Maid costume, however, is a very short and clingy dress (ideally silk or closely resembling it) trimmed with white lace. If panties are worn with it, they are white and ruffled, and the dress is short enough to display them, especially when the woman bends over. Black fishnetstockings and black shoes with high heels complete the ensemble, with trim typically including a tiny white apron attached to the dress, and white fringes on the hems and (revealing) neckline. Common accessories include a frill worn in her hair, a featherduster, and sometimes white lace cuffs and collar. The cuffs are not attached to the dress, if the dress has sleeves they are short and puffed. A corset may be worn underneath.

Sexy uniforms are sometimes worn to costume parties and sometimes in BDSM sexual roleplay (whether on brief occasions or as a routine form of servitude to the woman's lover). They enjoy a wide popularity and are available from many sources.
