So far I've seen a couple of items for prim breasts made to go with a particular mainstream outfit. I desperately need to take better notes, because I can't remember the maker of one of them; the other is a Foxbean Laboratories product designed to work with a particular business suit.
I hope that happens more often. (There is a company, Sharp Dressed Tits, that does custom adaptations to third-party outfits of your choice.) My dream is to be able to walk into someplace like Nicky Ree, RFyre, or the Crystal Queendom and be able to buy anything I please, knowing I can use it with my prim breasts.
