Seeking Loose Legged Trousers and Shorts

Hello everyone. I’m trying to find an online supplier for a pair of trousers, custom-made to size for a larger gurl. There are plenty out there that cater to us ‘gurls’, but I’ve just been reading posts with horror stories about suppliers like ‘Milano’ etc., and wondering if anyone knows of one who lists something along the lines of my requirements as a stock line??: Loose leg trousers / slacks / pants, quite high waisted, snug around the body but full / loose (boot?) legs and preferably with a rear zipper but with some room in front for ‘those’ bits. Unfortunately about 2/3xl size? I thought I’d add that I’m also interested in some 1940s/50s style shorts. Again high waisted, with wide / loose fitting legs but VERY short “very” short. These are for my ‘Hooker’ outfit. Any suggestions?
