Dude. No. This will never happen.
Yaniv has Narcissistic Personality Disorder. Those fuckers can't be taught how to wipe their own arses, let alone be taught what to wear. Everything that a NPD wears is the height of fashion, because they're the pinacle of human beauty and everything looks amazing on them. As far as they're concerned, the horrified stares of onlookers are actually stares of lust and envy. Yaniv truly believes that he's the height of feminine beauty when he's wearing slap and a ballgown and that all the men and women around him are checking him out, as opposed to merely trying to figure out what the fuck monstrosity it is they're looking at.
Yaniv can't be taught because he's incapable of learning. Thinking that some overworked social worker is going to teach him how to wear a fucking bra is naive, to put it mildly.
