I think maybe they meant that Yara is putting more effort into her appearance upkeep than they think ugly folks do 😬 and she can’t do anything further to be attractive for Jovi? But I agree it doesn’t make sense because nobody could argue that Yara herself couldn’t be a stripper. If she weren’t “banging” (or just of a different body type than the strippers Jovi is into) she’d have even more of a reason to be insecure.
