I found this at RDNA.  It's not really an under garment, but if you can't find anything better, you might be able to do some post work on it.  It's for Aiko, but you should be able to use the dials and magnets or the tailor, or wardrobe wizard to resize it.

I'll look around for another 10 minutes or so and then I'm heading to bed. If you haven't found something by the time I wake up I'll look around a little more for you.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
