One of my LFW favourite girls to photograph (hence lots of photos!), the crazy beautiful and talented Rosalind Jana: student, writer and editor of Clothes, Cameras and Coffee blog.
Roz loves wearing mostly vintage, ethical and second-hand/charity shop finds (clever, clever girl to unearth such fantastic pieces), and, fittingly, she covered LFW for Oxfam (Roz writes for them regularly).
Recreate Roz's look (if you don't have time to trawl vintage/op-shop's yourself - patience and dedication is the key to finding choice vintage pieces, I think ;):
Sass & Bide The Introduction colourblock pants or Alexander Wang trackpants (love classic navy for evening with a great heel) or Topshop silk jogger by Boutique
Textile Elizabeth and James Austin shirt (super feminine and sweet) or Reiss Kara nude polka dot shirt
