1. David Koma Top where you can buy at Stylebob.com is my expensive choice. The cut is wonderful and the voluminous ruffled sleeve combine makes a stand out choice. I would love it with a leather jacket and a strech-crepe skirt in white or nude.
  2. TopShop long sleeve ruffle top is my cheaper version of the first one. It's a very cute but more edgy style with a cold shoulder.
  3. Vera Wang Jumper is so cool and comfortable, that I feelt in love at first time. The material is merino blend cold and it has side slits and ripped  cuffs.
  4. High neck cold shoulder sweater has long sleeves, a interesting loose of the shoulder cut and you can wear it with a simple white shirt under, also for your office work ;)
