i <3 whitney

i'm not ashamed to say that i devour Mtv's The Hills every monday. it's totally terrible television, but i'm addicted, what can i say? and of the ladies on the show, Whitney is most definitely my fave one. If for not other reason than her incredible style sense (and she seems more real than the others). anyway, this post is not necessarily about The Hills. It's about my obsession with this cardigan that she's wearing here. i...must...have....it. so i'm sending out the question into cyberspace...if anyone knows where it's from or where i could find it...please please please enlighten me. its probably vintage. and i'm already plotting in my head how i could craft something up to resemble it if i can't get my hands on the real thing!
