Uniqlo does a great number of HEATTECH products, which are made from clever material that keeps you warm when it is cold and cool when it is hot. Most of these items are plain and place practicality over style and are ideal for layering, but with her distinctive patterns, the Orla Kiely tops are good enough to wear on their own. Choose from either a turtle neck top or long-sleeved crew neck t-shirt, both available in a range of Kiely's familar designs. The tops cost £12.90.
