Taipei and Hong Kong are the places to get them done. Taipei is preferred because it's cheaper. Some people (engaged couples) even make special trips to get them. Here are just a few of the many, many entertaining examples I found online:
I don't think I'll have any turtleneck guys unzipping my dress, and I don't plan on wearing disco pants - but I think you get the point.
For $2,888 (about $100 U.S.) I get four costume, hair and makeup changes. That's comparable to what my college graduation prints cost, and you don't get any costume changes with those. In fact, one of my four proofs was unusable: When the photographer told me to tilt my head and "gaze into the future," my lazy eye wandered astray. Glamour shots should be much more fun.
I hope the studio has four American-sized outfits. I'm bringing my own shoes.
I'm very, very, very excited.
