Even at my lowest weight I have dip hips.I'm sorry but it IS her fault. When I used to be heavier I had violin hips or hip dips like her. When I lost the weight, the dips also disappeared and now I don't have them anymore. So yeah, just another example of how her lazy attitude influences her body...
You can minimise them with weight loss and by toning up, but for some people they're there for life. The severity of hers comes down to her laziness and crash dieting, but it is genetic and isn't always something you can control and get rid of.
I agree though, they would be a lot less prominent if she put effort into her appearance all year round and not just before VS.
