lol, yeah, cod pieces have come a long way, but sometimes you need low ARC.
i have 2 kilts from MC leather that have good aprons, and yeah, they're very slightly curved prims and the flex is set to move sideways, so it looks pretty convincing. i also have a lot of nice ones i don't wear because they need adjustment. just got a beautiful one in the twisted hunt, but it's essentially a butched-up gown.
