i adore that cardigan but it is completely sold out in the stores (it went on sale there) and online they only have larges and extra larges. It is beautiful in person though!
If you love them, don't wait... get them now... especially the top. I picture it selling out before it goes on sale, and since it's a fairly new top you might be waiting a while for a sale. If the cardigan is sold out in your size online, just call the anthro 800# and they can track one down for you from one of their stores.
On the Anthro site it always shows that everything is available, but once you put it in your cart it will tell you what sizes are available.
That irritates be soooooooooo badly about their website. You get excited thinking it is available and then it pops up that it is not. UGGGGGGGGGGHHH!!! Ok, I feel better now.
