Dos and don'ts at the "I don't know how she does it" premiere

Even though this is not one of her best looks she looks gorgeous on this dress by Antonio Berardi.

Olivia Palermo is looking stunning with soft colors and a hint of darks on sandals and rings / Jessica Szohr looks amazing with her new long bob and / Red is definitely Emma Roberts' color

Sophia Bush would have been right just wearing one of the sequence pieces, just the shorts with a nice simple white shirt, maybe / Christina Hendricks  is too shiny and showing too much cleavage in a Vivienne Westwood dress,
