And if you use a second skin effect much like the painted on Bra that V4 wears then you change the length of the mask and that changes the height of the sock.  And it follows the bending just as the model since it is the model.  Different masks can be made to make parts see thru such as fishnets.  About the only thing you need to make is a toe cap to hide the toes the rest can be a texture map.
