Fairly amazing, am I right? I think these are homemade by N, and I saw them at HyperGender's Necromance show on February 6, 2010 at WoW Cafe Theater. Part of a Lady Gaga performance piece.
Pasties are adhesive coverings applied to a person’s nipples. Pasties vary in size, shape, design, material, and color. They are usually applied with a special glue, spirit gum, or various tapes.
Pasties are worn by many neoburlesque performers. Burlesque pasties may also feature tassels, which can be twirled by the performer, although many other materials are used to customize and personalize performers’ pasties.
[--From wiki and me]
Merriam-Webster (circa 1954) defines pasties as: small round coverings for a woman’s nipples, worn especially by a stripteaser.
