I wear a cardigan to work almost every day, even if it is just thrown in my bag as an extra layer in case it's chilly. I love this cozy Textured Short-Sleeved Cardigan from Banana Republic. It looks cozy but not too slouchy for work.
This DVF Linda wrap dress is such a perfect combination of sophisticated and flirty. I think you could transition it from work day to date night by pairing it with a black cardigan.
I love the Cafe Capri in Wool from J. Crew so much that I would almost be tempted to try a bold colour like the tangerine above.
I would love to have this Greer Cardigan from Tory Burch in my work wardrobe. Hmmm maybe it will show up under my Christmas tree.....
