Cindy Willis, Sandra McConnell, and fashion designer Catherine Malandrino hosted this year’s annual Southampton Hospital summer bash (benefiting the department of emergency medicine) under the great whites (tents that is) in Southampton.

The ultra-hip after-party, hosted by Cristina Greeven Cuomo, Andrea Greeven Douzet, and Rob Fox, and featuring a cabana-club theme, was packed with the younger set boogying the night away.

The socially chic included: Gervaise Gerstner, Chuck and Ellen Scarborough, Peter and Jamee Gregory, Tory Burch, Jim and Barbara Bennett, Barbara and Vince Sforza, Somers Farkas, Alison Shaw, Betsy McCaughey, Robert Zimmerman, Stewart Lane and Bonnie Comley, Mildred Brinn, Heather and Steven Mnuchin, John Kastanis, and Dana and Dr. Patrick Stubgen.
