Pant Slips

you can wear underwear or naked black just make sure there is no lace or other ornament on your underwear that way it cannot be seen through your pants.

I do not think so, but you can wear nude / beige underwear if the color will not show through

DO NOT wear white underwear. Contrary to popular belief, they appear so bad! Wear flesh-colored panties transparent can be purchased in most department stores! No visible underwear, and no visible lines ... sorted darling! :)

I've never heard of pants slips, but u have to wear either underwear or naked black ... or if u do wear a bright color that u think will be visible in the pants u could put a pair of black leggings underneath.
