I think I'm getting there with the collar and bow tie. The next big challenge will be the tights, specifically having them stay close to the skin in the crotch (which they're already kind of doing here, but certainly not in the pose above) so that the lingerie can go on top of them. Another option would be "built-in" tights, but first I'll try to keep them separate, which makes for a more versatile garment.

-- I'm not mad at you, just Westphalian.
