I'm looking at the contours of Nancy Wu's belly, and my first thought is, that if she ever had a baby, she would have a gut on her that wouldn't go away. She looks skinny on the upper half of her body, but her lower half is actually disproportionately larger. Thus IMHO, in her later years she's going to be one of those big butted Chinese women.
Yes, but I'm not just talking about her abdominals, but rather, her entire Pelvic Girdle; just look at her from waist down, including her hips, compared to the other woman. Wu's shape is substantially more robust. In later years, that normally translates into a big mid drift and large butt.
