Fair warning for buying trousers made for the opposite gender as what you were assigned. Women’s section trousers will have a bigger difference in the waist circumference and hip circumference. This could make them bulge/flare weirdly at the hip (just a guess, I have the opposite problem where the top of the waist band will have a gap even if the bottom of the waist band is snug. AFAB mostly buying men’s trousers.) Might take a while to find ones that you like, or you could get them tailored. But at that point, it might be easier and cheaper to get longer inseam shorts and have them shortened. Re hemming can even be done yourself if you have access to and cursory knowledge of a sewing machine, or know someone who does.
