Is it possible to build a curvy silhouette from this?
I have no volume anywhere. All of my peers have some sort of curvy shape, be it pear or hourglass, and I feel as though I can't really change much because my hips are far too narrow. Even with calorie slurpus and a legs focused workout, maybe I just dont hold any weight on my lower body. I'm scared of bulking and just getting a bigger stomach, keeping the twig legs and flat ass.
I don't know if measurements help, but:
Shoulders: 80cm
Waist: 57cm
Hips: 80cm
Weight is at 40kg at 1,50m
