Sofie Valkiers of Fashionata, before A Show, NYC, February 2015.
A lovely way to brighten up the grey (in London anyway!) winter days: cropped brightly coloured trousers. 
Recreate Sofie's look (kind of):
Opening Ceremony Crepe wide leg pants, Rachel Comey Bishop Wide leg pants, Acne Studios Odette linen pants, Roland Mouret Rew cropped wide-leg pants, Isa Arfen cropped linen wide-leg pants, or ASOS Cropped kickflare 
Platform boots: Marni Paneled leather platform boots, Miu Miu Suede platform boots, Marni Platform Ankle boots, or KG Kurt Geiger Sugar black platform boots
