Blake Lively, Penn Badgley & Irina Shayk Show Off Summer Style At The Cinema Society & 2(x)ist Screening (PHOTOS, POLL)

The Cinema Society & 2(x)ist held a screening of "Twelve" in NYC on Wednesday night, which gave stars another opportunity to show off their summer style. There were plenty of dresses, pumps and even some chest hair...and some attendees looked ready for fall while they were basking in the July heat (bad decision!). Take a look at who wore what and tell us who was best-dressed.
