100% agree, but who am I to police others. If Disney CMs are doing their jobs and a guest is breaking the rules, someone will ask the guest to put on appropriate attire, whether the CM at the gate, or somewhere in the park. I would hope that people could police themselves, but generally, those who refuse (and I'm not implicating the OP here) won't be dissuaded on this forum. Some people feel the need to shock others, or do inappropriate things. That's their right until it becomes other people's problem in some way. (How's that saying go? Your right to swing your fist stops where my nose begins... or something like that.) That's when the authorities, Disney CMs in this case, should step in and address the guest. I know that makes me sound like a total square. I'm not, but if I do something and get called out on it, I'm not going to double down and be a jerk. Usually when I do something wrong, it's not intentional so I have no issue correcting myself.
Btw, I can appreciate the female form as much as any guy, but I think it's a matter of context. Disney parks isn't were people's "forms" should be flaunted, but it's not for me to police.
