Jeans and shorts and bathing suits

I'm switching over to mid rise jeans because I come to realize my butt crack is to long for low rise after 21 years of blessing everyone with my crack know matter how hard I try to hide it ! I'm also wanting to find a good brand of shorts that don't give the look of having a small dick lol. My thighs are thick so maybe no cootchie cutters. Also i have a little bit if muffin top and want ti try and hide that with a thicker band on my bathing suite any good brands for not fat but a little bit of chubby girls? Does anyone have any good brands I should try? Thank you!
