I love this look for work - classic black dress, black tights, and boots. I especially love the neckline on the dress, the long sleeves, and the length (not too short - still looks polished and professional) ann taylor dress. $98. long necklace.
I like this look: all neutrals, clean. Haven't tried turtlenecks/mock necks in a while, might be worth a shot. Ann Taylor knit jacket (385563), sleeveless ribbed turtleneck (384035), devin refined flare trousers (376131)
