I used to see a lot of these floating around but haven't noticed one in ages.
I'm wearing
Dark green long sleeve blouse - Zara
Dark green tailored shorts with faint polka dot pattern - also Zara
Short (almost cropped) tartan-y blazer - a charity shop find
Black tights - New Look
Black ankle boots - Topshop
Will chuck on big dark red scarf (River Island) and suede dark red gloves (Accessorize) when I pop out again in a bit, with a green coat and a black messenger bag.
I feel a bit like a farmer's wife, but I'm quite enjoying it. 
What are you all sporting today?
