Martha Hunt, after Badgley Mischka, NYC, September 2011. 
Love Martha and her off-duty style. Simple striped shorts plus comfy loafers = easy weekend wear in the city.
Recreate Martha's look (kind of):
Show off tanned, toned legs in Rag & Bone Cohrell shorts , J. Crew Dapper striped shorts, Rory Beca Orissa silk running shorts, ASOS striped mini shorts or Victoria Beckham Denim sunset striped shorts
LNA Deconstructed zipper t-shirt  or T by Alexander Wang classic t-shirt with pocket
The loafer/slipper without socks or tights is a great alternative to sandals in the summer (and entirely useful if you have forgotten to have a pedicure ;) — Barneys New York Co-Op loafers, Marc by Marc Jacobs New Vintage glam loafers, UNIF Hellraiser flats (best for fending off unwanted attention on the Tube/Subway/Metro!)
