Hi there!
What this is, is set of BoMR tattoos I created to give my Project Regalia avatar a nice pair of dark nylons and some sheer panties.
Dress for success!
The Project Regalia body was essentially created for furries, and accordingly comes with paws (and optional hooves), so the nylons I made have a nice lacy band that goes around the foot to leave your pawsies or hoofies free. :)
By popular demand I've updated the panties and nylons to use the Bake On Mesh - Regalia system. You will need a current viewer for Bake On Mesh functionality, and the BoMR applier here:

(It's free, don't panic!)
Once you've set up your base skin, simply adding or removing the various tattoo layers will add or remove the undergarments - easy peasy!
