Miss Peony Lim, before A Show, Somerset House, London, September 2012.
'Tis the season for a little plaid... update a traditional tartan kilt like Peony is wearing (this is an inherited kilt from her mama's closet) with some studded accessories (helllloooo Valentino clutch — I do love you!), strappy heels, and a crisp white blouse.
Recreate Peony's look (kind of):
Check/Plaid skirt: Thakoon Addition Plaid miniskirt, McQ Alexander McQueen tartan pleated skirt, Boy by Band of Outsiders pleated check skirt, ASOS check midi skirt,  B + AB check skirt, Burberry Brit kilt skirt,  J.W.Anderson plaid midi skirt, ASOS tartan mini skirt 
If you like a kilt shape but not the plaid, try Joseph Saki mini kilt or this kilt skirt by Topshop.
Valentino studded leather clutch (in beige), black or incredible fuchsia (wowsers!).
MHL by Margaret Howell cotton poplin shirt, Boy. by Band of Outsiders cotton shirt, Theory Macina luxe top, or ASOS shirt
Rag & Bone hammered triple wrap belt, Diane von Furstenberg Haley studded wrap belt, B-Low The Belt Grayson studded belt
p.s. I think a pair of cute heeled ankle boots + a coat would look fab with this look in the depths of winter.
