A girlfriend of mine referred to wearing lingerie as being negatively dressed since it frames and enhances to go above and beyond plain nudity.
On women I prefer any. (I've dated to many who don't appreciate the allure.) Garterbelts & stockings are winners, bustiers, teddies, chemises, anything that can be worn during the act scores extra points.
Color depends on hair: blonde hair = black lingerie, brunette hair = black or red, red hair would require black, black hair would be red.
General color preference (in order): black, red, white with shiny/metalic color variations behind (blue, purple, etc).
For feel I prefer the slipperyness of many polyester articles, which also benefit from less cost than silk.
