Advice welcome... I'm a size 12 with a flat bottom. Whatever shape pants (knickers) or trousers I wear, I'm constantly digging them out of my bottom. Tried a pair of trousers on today and while they fitted everywhere else, they were obscene on my bum! I am long waisted which might be the cause of this problem, but with short legs. I definitely look better in dresses but I would like the option of trousers. Ideally, slim fit with a crop. 😱😵😁
