International Fetish Day is observed on January 15, 2021. International Fetish Day is a day supporting the BDSM community. It originated in the United Kingdom as "National Fetish Day". The first International Fetish Day was held on 16 January 2009 (the third Friday of the year).
The main purpose of International Fetish Day is to increase awareness and support of the fetish community, whilst also opposing the new law criminalising possession of "extreme pornography". BDSM is a variety of erotic practices involving dominance and submission, role-playing, restraint, and other interpersonal dynamics. International Fetish Day is also designed to encourage members of the community to be more open about their sexuality.
On National Fetish Day, one of the main aspects is that members of the community wear an item of purple clothing as a sign that they are a member, in an event known as "Perverts Wear Purple". The main benefit of this act is that it indicates that someone is a member of the community whilst being "Vanilla" at the same time. Purple is a colour widely used in BDSM circles.
