There are no supermodels anymore and there hasn't been since someone like Agyness Deny or maybe Cara.
Obviously the golden age of Cindy, Claudia, Naomi and later on Kate is long gone.
Bella is just a Nepo who starved herself and had extensive plastic surgery all over her face and body. I don't even think she's especially tall? Her sister is even worse though.
I think to be a good model you have to not want to be a model. Like you get spotted and scouted and just happen to have the look. Anyone desperate to do it probably hadn't the right look naturally.
