You could tell this was a weird sex thing when his woman get-up consisted of a garish wig, corset and a dog collar.
Incidentally he's been wearing the same dog collar for two years now. Do you throw dog collars in the wash or is the sweat and grime part of the appeal?
If it is a kink thing (which this is Jim, it is), well usually you hand wash it after or before you shower, usually your evening shower, since unless you're a fucking troglodyte you should fucking shower at least twice a day, once in the morning so you're clean for society, and once in the evening to remove the grime of contributing to society. Usually this second shower is when you'd do such since you don't have time in the morning, and you need to do so by hand since tossing it on a washer would damage it.
Generally if you're a functioning member of society with respect for others you'd wear that an average of 12 hours a day, since you're not in the privacy of your own home the other 12 (in western society we're typically out of the house 12 hours a day unless unemployed or working from home). Usually putting it on right after your evening afterwork shower until you leave for work the next day. For Jim he's likely at home more, so he likely wears it whenever he's not leaving to go to a gig or train. Taking it off to shower, wash it, then put it back on. Except if Jim had such respect to remove it to go train or go to a gig, he'd also remove it during times he is on camera, which he doesn't, so he's also probably wearing it in public.
He shouldn't shower with it on either way, that's bad for the pleather. It'd disintegrate faster, it is also bad for real leather too. The water and oils of your skin would also tarnish the metal, even stainless steel, if it was went in the shower with him and wasn't washed. Those same oils, for the record, would cause it to fall apart if he never washed it since, unlike dogs, we don't have a layer of fur to protect it from our skin oils. So he's either washing it, or replacing it.
I'd say it is a Jimquistion only costume piece, something to hide his Adam's apple, except we see it in twitter pictures and streams enough to know it is a consistent accessory. It isn't a constantly worn thing though, which is the only reason I might doubt it is a kink thing, since normally being collared means you wear it constantly, unless he has something else discreet he swaps it with, but even then, if he had that type of concern or consideration you'd expect to see more of it for the camera and public. Unless he just doesn't care, and some days simply forgets to swap, remove or perhaps even put it on.
Also, fun thing, in the kink scene pink collars aren't common on women, only sissy men. It's a signal that you are male and are degrading yourself by dressing like a woman. More evidence trooning out is a fetish here.
