I will not apologize for poaching on another thread. I think the romantic Mr. Hu overdoes it in his praise of Japanese girls but these things are always subjective as well they should be.
For me, the last time I was in Beijing I was really impressed with the elegance of the modern Beijing girl and I place her ahead of the Shanghainese (sorry) and Tokyo girl in stylishness, grace and mystery.
The modern stylish Beijing girl has a greater sense of independence, longer legs and a fuller body. She is more confident and cocky. Unfortunately I am not of an age nor marital status where I can do more than observe but I thought I would pass my observations along.
