As the 2008 Olympics approach, China is looking for hostesses for the medal ceremonies. The criteria:

...[W]omen of uniform height with neat bottoms and minus body art and ear studs. Glossy skin was another asset.

“Bone structure and height should be uniform,” .... “For example, we don't want any wide bottoms.”

These are the kinds of things that remind you just how different our cultures are. I would guess that people who recruit models for trade shows in the US use the same criteria but wouldn't dare admit it.
