If you like a little Sci-fi, I might be able to point you in the right direction. The latest group gift at Prey for men has a Science Fiction feel to it that would make it ideal for roleplay, though I’m sure you could get away with it for every day Gothic wear as well.
This outfit comes in several separate pieces… you get the pants, top, and shoulder metals all as individual pieces that can be worn separately or together depending on the look you want. It only comes in standard mesh sizes, but I didn’t have any trouble using alphas to get it to fit my Slink mesh body.
Pick this outfit up free with your free group join at the Prey mainstore in the men’s department.
