Transvestitism is a form of self-expression where individuals dress themselves in apparel typically associated with the opposite sex. It involves wearing underwear, which is usually associated with femininity. This may include thongs, bras, corsets, stockings, and additional types of frilly innerwear. Transvestis accept this interest as a means to explore their personal gender identities or for erotic arousal. Participating in crossdressing lingerie can provide a sense of autonomy and assertiveness for those participating.
