It's all about the cardigans for me at the moment, the changeable weather combined with the arctic air-conditioning on my trains means I'm either baking or shivering and you can't beat a cardigan to slip on and off. I'm loving Dorothy Perkins' retro blue cardie, which also comes in olive green, grey and white. Perfect for adding an accent of colour to a neutral outfit. A longline cardigan looks great with skinny jeans and makes summer dresses more casual, and M&S' one is only £25, for a more fashion-forward look pick Topshop's navy wrap. CandySays' yellow rib cardie will look fab with some turned up dark jeans and a white vest for a retro summery look, equally bright is French Connection's pink cardie.
