As you may know, it is QUITE difficult to find screen accurate tops worn on the show Buffy the Vampire Slayer. But one of the easier Buffy items to find is the D&G leopard cami she wears in the season 2 episode Ted.
The top is cotton and leopard print. There are similar tops, by D&G, but the one Sarah Michelle Gellar wears has a keyhole tie near the neckline.
