i wondered if this was too off topic but then i looked up at the top of the page and saw "The Kitten, The Witches, and The Bad Wardrobe" and figured it was okay. No direct Willow or Tara mention (in fact on the character Buffy directly) but there is a picture of the BTVS stylist so you can sit and glare at the woman responsible for the wardrobe *laughs* or be thankful that willow and tara aren't forced into mindless trends that make them look (as much as they can) like every other young female on tv...
also there's a pic of Buffy and Willow from this season. and a reference to Dawn's Hello Kitty tee earlier this season *smile*
as for any possible spoilers, unless you're into the semiotic interpretation of fashion (Cynthia spills a few small developments in Buffy's wardrobe later this season), none to be seen. anyway, enjoy trying to get inside the woman behind the bad wardrobe's head.
