That dress looks so great on her (and the whole look). I love, love, love that dress. Tried on the blue/black coat in that fabric today.
Update on the prices (I put it in my NY post but that info was wrong). I bought the grey leg and brown top wool today with toes and they were $95 (no tax on socks in NY -- woohoo).
They come in 1, 2, 3 -- I really wanted 1's but they were out so got 2's -- I'm a size 6 1/2, 7 and they're just a bit long in the foot if I wasn't wearing them with boots. Yoki at the Fifth Ave store helped me and she really dug around for the 1's -- their number is 212 664-0020.
The wool is not thick (and they stretch out on your calves).
