Well…either Wheel of Fortune has a dress code, or people watch the shows on TV and decide how to dress. I am thinking however, that before the people go on either show, the correspondant from either tells them what to do, how to dress etc.
I don’t know either show, but I can’t believe contestants would not be thoroughly drilled in how to dress, behave, etc. They’re performers on a commercial program. Appearance is not something that would be left to chance.
People going on Wheel of Fortune know ahead of time that they will be contestants, and they have time to get TV ready. The Price is Right’s thing is that anyone in the audience might be a contestant, even people dressed like slobs.
On wheel they have an opportunity to bend over and show their boobs. FAR too many choose this option. Perhaps, they have found it to be an effective strategy in their lives.
