I disagree with that definition, wiki definition makes better sense:
Transvestic fetishism refers specifically to cross-dressing; sexual arousal in response to individual garments is fetishism.[1] Transvestic fetishism can occur with or without gender dysphoria[1]; that is, there are people who experience sexual arousal with cross-dressing and want to become the other sex, and there are there are people who experience sexual arousal with cross-dressing but do not want to become the other sex.
Some male transvestic fetishists collect women's clothing, e.g. nightgowns, babydolls, slips, and other types of nightwear, lingerie, stockings and pantyhose, items of a distinct feminine look and feel. They may dress in these feminine garments and take photographs of themselves while living out their secret fantasies.
