I have to add, that it is very important to undersand what situation you should wear Qipao. For example:
Don't wear Qipao to Chinese restaurant, otherwise you may be mistaken as wairtress.
Don't wear a long silk Qipao when going shopping, that's called over dressed. Don't wear Qipao when going to Karaoke. cause that's the favorite outfit for the "xiaojie" or hostess there, too.
***** Don't wear Qipao when a nicer looking girl is wearing it too, because you don't want people making fun of you by comparing you to another girl. *****
***** Don't wear Qipao when you are really out of shape, ***** there're better traditional Chinese clothes for you, such as a shirt, it makes you look slimmer
