Jeans for a flat bum

[Joliv123]

I have lost some weight, yeah and feel much healthier, I’m a small size 12 now, about 5 ft 4 , I am quite big chested, and want to balance out my shape, years ago I had some jeans with flaps and button back pockets which created more material on the back pockets making my bum look a bit more rounded , does anyone know of jeans like this on sale now please?

Taking this from a different angle, it was my NY resolution to swim twice a week. Hope this isn't TMI, but my bum is definitely more rounded. So, sorry, I can't help with the jeans but I can recommend swimming
