I just joined DIS and I found this thread. I think this is hillarious because my mother and I wanted to write a book with each chapter covering a different inappropriate thing that is done at disney including some people's clothing. I sympathize with some of the posts that say they don't really care what people wear but some things are just completely inappropriate; not just in the park but in public in general. I will demonstrate:
3 years ago, while at Epcot just outside of the Rose and Crown I notice a woman. She was wearing a dressy black top with dressy black sandals and...drum role please.....

a pair of sheer (completely see through) black guazy pants with a black thong underneath. Wait wait it gets better. She was with a man who was wearing gray dress pants and a nice button down shirt. It was about 7pm and they were standing at the reservation counter outside of the Rose and Crown so I assume they were going to dinner and this was her idea of dressing up.
I have to say that I don't think there's anything wrong with wearing certain sandals or dresses or skirts and I think dressing in something a little nicer for dinner is fine but this crossed the line in polite society everywhere.
Do I win?

Do I win?
As a side note I think those skirts, shorts and pants with the words written across the hiney are inappropriate for little girls. I'm 26 so I am not an old prude and I like dressing up and going out but I don't think it is ever appropriate to create a situation where people are invited to read the rear end of a 10 year old or a 16 year old.
