Hilary Rhoda (Patrick McMullan)

In a sea of short-hemmed summer frocks, Ms. Rhoda looked elegant in a floor-sweeping taupe number at a Hamptons screening of Robot & Frank hosted by the Cinema Society and RentTheRunway.com. It wasn't exactly basic beige, though--Ms. Rhoda's floor-skimming number was set off by a riot of multicolored jewelry around neck and wrist, fitting the casual mood of the soiree without looking like a beach-day refugee.
