doesn't it just depend on your own preferrence?  If you want to be traditional, have a qipao- styles at www.goodorient.com are more modern.  How many dresses do you want to change into?  If you want a ball gown, I would go to stores like Macy's rather than bridal shops because anything labeled with "wedding" tend to be more expensive.  I am only going to have a qipao in addition to wedding gown.  Just remember, the more dresses you change into, the less time you have to relax and enjoy the wedding itself...
