The above art is the first sketch of the fourth batch of clothing and underwear images. They are; a latex maid's outfit, a latex nurses outfit, a leather bustier/shorts combo, a latex business-suit, leather crotch-less boxers, frilly latex panties, crotch-less latex panties, regular latex panties, and finally leather buckle-up panties. There may be some alterations to them, mostly just the business-suit having latex pants, but this is a general feel of the various clothing pieces. The artist Silverjile has graciously cleared me posting the early versions.
