On the actual topic, I will say this:
THe tour-guide we had for the Keys To THe Kingdom Tour at WDW was of the generously proportioned persuasion, but we were more concerned about her rude manner ** than her outfit, which was (IMHO) flattering to that particular figure anyway.
**(Derail Warning) BTW: What happened was this - We were stopped in the HM Courtyard and she was in the middle of a very long yarn about the hidden mickeys in the WDW Mansion. Stoat has heard all about these from me ad nauseum and so he stepped away fromn the group for a brief time, and stood next to some other camera toting tourists, and snapped a pic of the mansion on this, the first sunny day we had seen at WDW.
She noticed the pic (the only one he had taken, BTW) and chided him abruptly in what I would call a "Old-fashioned school marm" manner, talking condascendingly to him as though he was a child and making pleading gestures with her hands. (I have a pic somewhere that I'll drag out.)
He was thoroughly shamed and it totally ruined the tour for him, and me. I realise he should have read the sign in the tour courtyard, but he was excited and distracted at the time. It's not even as if he was holding up the group, he just took a quiet moment to snap a pic we had not been able to get the whole trip. That said, there is a right way and a wrong way to chide someone, and she was OTT in my opinion. She could have asked him to stop quietly without making a dramatic example of him. We didn't complain to City Hall about her, as we were shamed into feeling guilty, but I had to suffer a miserable day for the rest of the day as a result
