Continuity mistake: Emily removes from her outfit the jacket and the dickey and leaves them on the couch before she gets booze (for some reason in another room). The dickey lies on top of the jacket, untouched and yet obviously in different ways in the various shots - look at it the first time, with just a little part sticking out over the couch and down its back, and then look at it when Emily comes back, and how the jacket and dickey are practically parallel.

Continuity mistake: When Sean is introduced for the first time, there's an obvious continuity issue with Blake Lively's hair over her right shoulder. (00:12:00)
Continuity mistake: At the beginning of the scene inside the Dennis Nylon mansion, Emily is wearing her bag on the left shoulder. She sneaks her way inside the "employees only" area, loses her cover (the guy bringing clothes upstairs), still with the bag looking the same, but the moment she enters Emily's office in a rush, she is wearing her bag across the chest, right shoulder strap, bag on the left side.
