Bro I have the same problem .. I got a skinny waist but a big ass and upper thighs ... Yesterday I went to try on jeans and it took me about 20 pairs to finally find ones that would work .. the waist isnt the problem is my bubble butt ... You could also get your slacks re taylored .. i get mine from menswarehouse and they will do it free for life if you buy a suit from them ... goodluck
