i think getting pants and converting them to... convertibles... is my only option as well. but getting cargo pants that fit well is a challenge in itself.

my biggest problems are:

long inseam: correctable with hemming

long rise: crotch to waist distance is too long on 100% of my shorts and pants. the average seems to be 12 or 11 inches. my distance is 9 inches.... i don't like having a baggy crotch area. this is why i wear compression shorts all the time and can't wear boxers as regular underwear.

overall length of shorts: i like shorter, less restrictive shorts

volume of pant legs: pant legs are always too big and appear billowy on me. I want skinnier pant legs. it's weird having slim fit shirts but big billowy pants on at the same time.
