What is the fetish sport #1? Aerobics or shiny leotards with shiny pantyhose

I mean official sports, not something like self-bondage 😉 Just to name a few:

figure skating (leotards – actually, they are called figure skating dresses, unitards, pantyhose, leggings, “high heels”)
gymnastics (swimsuits, shiny leotards)
rhythmic gymnastics (leotards, leggings, unitards)
ice skating (hooded unitards or catsuits)
aerobic (swimsuits, leotards, shiny pantyhose)
synchronous swimming (wet leotards, swimsuits)

Let’s start with aerobic.(See other candidates)
According to the official rules:

Attire of aerobic athletes should follow as per FIG Code of Points (2005 – 2008 2.3 Dress Code):
Women must wear a one-piece leotard (colour optional) skin colour leggings or tights must be worn, and white socks. Optional tights are allowed for InterClub. Form fitting body shorts are allowed for InterClub.
Men must wear shorts style unitard or body shirt and short pants.

Attire for Pair/trio and/or group athletes should be identical (as described in FIG Code of Points). Optional tights are allowed as well as form fitting shorts for males and females in National Development Pre-Novice, Novice and FIG Age Group 1 category. FIG Age Group 2 and FIG Open categories are FIG requirements

Not that I have seen any photo’s of men wearing pantyhose during aerobic competitions (apart from the one at the beginning, not sure if it’s aerobic and not ballet, though), but at least it’s officially allowed.

Children and adults, boys and girls, women and men in shiny tights and shiny leotards! Sounds like an ultimate fetish sport! If you have passion for tight closing and athletics – this is the way to go!
