Aimee, who has the stunning blog, Song of Style (helloooo beautiful, smooshy Californian light!), before Lacoste (I think), NYC February 2012.

This was the day of THE SNOW. I think Aimee was as happy about the snow as I was! Love her primary colour blocking and the floral jacket peeking out from underneath her gilet. I think all of us layered on as many clothes as possible the day of THE SNOW although (most) of us didn't pull it off quite as cheerfully as Aimee did.

Recreate Aimee's look (sort of):
Alice + Olivia Kathryn yellow high-waisted skirt
Sonia by Sonia Rykiel colour block sweater or Acne raspberry pink Ry angora blend sweater or ASOS green angora sweater

How Aimee has styled her outfit might not work for everyone (particularly newbie colour-blockers who may not be so confident with combinations of brights) so a skirt or a sweater in a solid colour is a good way to ease into the trend for summer.
