Nobody will have the same answer. AFCENT wears OCPs different than us in AFSOC. And I met a few ACC dudes who're authorized OCPs as UOD and they wear it differently as well when it comes to patches, badges, and tan vs brown boots, tees, and belts.
Previously in AFSOC, Ratings and CEA badges (aircrew wings) were mandatory and no others were authorized. A few months ago additional guidance was released saying that AFSC badges were optional all. (Excluding wings which are always mandatory). They are all or nothing when it comes to sew vs velcro. If you want your badge sewn on you'll have to sew your name tapes and rank on too. The other option is to get a velcro patch sewn on and velco your badge on. Either way will require some sort of alteration.
AFSOC also wears Coyote Brown boots and Coyote Brown belts, while most others wear tan still. My squadron bought me a belt very similar to this but I'm honestly not sure what other people are wearing.
