We always look forward to a red-carpet appearance from Emma Stone. She continues to push the envelope with her style, and this time she offered inspiration on how to make our cocktail dresses more casual - by layering a simple tee underneath! Emma stepped out in Lanvin for the NY premiere of The Croods, where she was joined by her co-stars and Blake Lively, who was in attendance to support her husband Ryan Reynolds. Watch on for the scoop! On Allison McNamara: Club Monaco blazer and top.
