About early twenties. Your hips will stop growing when the rest of your bones do.0

Personally, I look nothing like my mother. Eye color, hair color, facial features etc. Everything about me favors my father. And my mom's hips are narrow, while mine are wide.
Hips (just like other body parts) stop developing when your body stops growing, which would be late teens/early twenties.0
