Garment fetishism or clothing fetishism is a sexual fetish that revolves around a fixation upon a particular article or type of clothing, a collection of garments that appear as part of a fashion or uniform, or a person dressed in such a garment.
The clinical definition of a sexual fetish would require that a person be fixated on a specific garment to the extent that it exists as a recurrent (or exclusive) stimulus for sexual gratification.
One who exhibits a clothing fetish may be aroused by the sight of a person wearing a particular garment, or by wearing the garment oneself which can be because of the look one achieves by wearing it or the way it feels while it is being worn (and might also get some arousal by seeing somebody in it and imagining how it feels). In later case arousal may originate from the way its fabric feels (see clothing fetish by fabric type) or from the way the garment feels and functions as whole (restrictive clothing being an example).
Others with a clothing fetish may be aroused by the sight of such garments, even without wearing them and in the absence of other person wearing them, and may also derive pleasure from collecting them.
