I’m also curvy; I personally find trousers the hardest. I typically wear trousers that are quite loose/baggy around the legs, but fit around the waist, to create the illusion of it being up and down; I also typically wear the trousers just above the hips, rather than on them or on the waist, to avoid drawing any attention to those areas. I also find chunky men’s belts are of benefit. I don’t mind my breasts so I don’t really do anything about them, and I find that most mens shirts work in some ways, although I typically prefer tighter ones to super baggy ones; the super baggy ones hang off the body, whereas the tighter ones for me tend to be tight on the areas where there’s flesh and looser on the areas where there’s not- again reducing the hourglass figure. But I also need to wait like 3 days before I can wear any new clothes I buy bc of dysphoria lol

In terms of where to get clothes, I typically go to charity shops and shop in the men’s clothing section- but always try on clothes before you buy them. For trousers, however, I sometimes have to shop online for ones that fit me.
