This is exactly what I mean in my post right above this one. Are you trying to say people have luck with white clothing not getting completely trashed looking at the slightest touch of dust?
You say "you can't have anything at all touch the coat while wearing it", so are you trying to say these $1000 white clothing people buy can accidentally touch the slighest bit of dirt on a car door handle and it wipes right off, or if you wash the item of clothing it comes right out? Perhaps that's my problem, I'm not instantly washing the clothing if that happens, but I sure as hell would never want to have to do that either.
