Brazilian model Flavia Lucini, after A Show, NYC, September 2012.
A bold red lip glams up a preppy, neat summer outfit. 
Recreate her look (kind of):
Sea Baby Flannel Gryphon blazer, Band of Outsiders Schoolboy jacket, Stella McCartney Iris blazer, Topshop structured blazer, or A.P.C. wool blend blazer
Madewell Elephant Eden boy shirt, Marc by Marc Jacobs Vivie printed shirt, or Chinti and Parker star-print cotton shirt
Vince Boyfriend Chino pants, Theory Rumer pants, or Alice + Olivia Anders trousers
