South Korean model Sung Hee Kim* after Peter Jensen, Somerset House, London, February 2012. 
Polka dots + denim shorts: wear now as is and for autumn/winter add a coat, tights and boots. 
Recreate her look (kind of):
ASOS shirt with spot print, J.Crew polka dot blouse, Equipment Diem tie front blouse (which is stars and stripes but still gives the same sort of effect!)
Rag & Bone/JEAN The Mila shorts, Genetic Denim The Lost Boy cutoff shorts or ASOS high waisted denim shorts
B-Low The Belt braided belt
Marc by Marc Jacobs classic lace-up wedge booties
*Sung has a really cute editorial photographed by Ilaria Orsini and styled by Sara Gilmour in the Summer 2012 edition of Tank magazine.
