You could hammer and saw the base cups out of sheets of high copper metal with a patina, sanding down the edges and add padding under it for comfort, then make the raised parts out of 3D printed plastic, then make a negative mold out of that, cast it in bronze, add it to the brassiere... so on and so forth. It's a lot of work, more than it's worth for cosplay or sex. I mean, unless you're a real mafia slug from space, is it worth the effort?

The original was based on sketches by costume designer Nilo Rodis-Jamero, the outfit was created by jeweler and sculptor Richard Miller using resin and urethane.
