Sometimes glamorous circus performers aren't experiencing the same glamour that the audience is, especially on hot days or in bright stage lights. I recently heard one of the other performers at a gig say backstage "I'm really glad that the audience can't smell me. Because I smell awful" to which another replied something like "Yeah, there's only so much layering of deodorant you can do before you just start smelling like Spring Rain and Sweat."
Also, you may notice that this post was super-late. Well, my computer broke beyond repair, and it took me until now to get a new one up and running. But now I'm working on a computer that's harder, better, faster, stronger, so it's all good!
