Buffy does not appear pleased
Who would have thought Rachel Green & Buffy Summers had similar taste in fashion. Well, at least in one episode. While getting the stink eye from Brad Pitt in the Friends episode "The One with the Rumor", Rachel Green wears a Laundry by Shelli Segal lace bell sleeve top. That same year, Buffy Summers wore the same top in the Btvs episode "Smashed". Both aired in November of 2001.
In a BBC interview with Cynthia Bergstrom, head wardrobe stylist for Buffy, she mentions that the Laundry Lace top was borrowed from the Friends wardrobe team. So in fact, Buffy and Rachel are not only wearing the same designer and style, they are actually wearing the exact same top. Special thanks to Obscurebookwyrm who reminded me of this fact.
