Oh my God, I love and adore this sweater. It’s the epitome of all her neck tie sweaters so far. I’m pretty sure it’s cashmere. I love the fact that the front of the tie is black while the back is white, so you can see both colors at the knot. If anyone can ID the brand, please let me know! Not sure it would be possible to find it for sale anywhere, 10 years after this episode aired, but you never know! Ebay can do miracles sometimes … lol
