Model Kate King, after Louis Vuitton, Paris, October 2011.
Love Kate's girlish white maxi skirt offset by the toughness of a denim vest — rummage through charity shops or markets for a vintage vest or deconstruct an old denim jacket from your wardrobe for extra street cred (and to show off your deconstructing/sewing skills!).
Recreate Kate's Look (kind of):
Current/Elliott The Sleeveless Snap Jacket, Rip it Up vintage denim vest, Moto Sleeveless denim jacket, ASOS Foldover sleeveless denim vest 
Michael Michael Kors crochet eyelet skirt (perfect with a denim jacket — sleeveless or not), Alice by Temperley Nina cotton maxi skirt,  Tibi maxi skirt,  L.A.M.B long pointelle skirt,  ASOS seamed maxi skirt (in white)
Rag&Bone/JEAN scoop neck tank  or Haute Hippie ribbed Longhorn tank
Add a carry-all tote: Chloe Madeleine leather duffle bag in toffee or forest green
