I think Olly knew his tennis white Xena Warrior princess outfit at London Pride was a thumbs down. Thus the last minute order of something else (that didn’t get there in time) and the public excuse that this was his “backup” outfit. As pornsick and deluded as his brain is, he still has eyes (and presumably a mirror) and must have realized how stupid and mannish he looked.
But as they say in the thee-ah-tuh, the show must go on lol! It’s really astonishing to me that he didn’t try that outfit on at home, realize he looked like the parody of a man in a dress, and decide, fuck it, I’ll just wear a pair of jeans and a top or whatever. I mean, he actually wore uncomfortable heels to participate in a march, potentially injuring his enormous feet. So obviously he was just lost in his narcissistic AGP fantasies and wasn’t thinking really clearly. And the rest is lolcow history!
