Jeans problem

OK I know this topic is stupid but I'm pissed off. I wanted to buy a pair of jeans. And what? All the jeans I tried on ended on my ass! Just like in the picture. OK, maybe I wouldn't mind if it wasn't the middle of the winter and if I had a figure like a model. So I tried them on, I sat on a chair and I saw my buttocks. Excuse me, but do other people really have to see my ass? I don't think so.
Maybe I missed some evolution women had in the past 6 months and they got rid of hips? Cheers
