15-year-old Abigail Breslin typically keeps it casual on the red carpet, but at the Breast Cancer Research Foundation's Hot Pink Party on April 14, the "Little Miss Sunshine" star opted for ultra glamorous.

The child actress -- who recently tried a much edgier look in Bullett magazine's premiere Femme issue -- walked the pink carpet in an off-the-shoulder Notte by Marchesa gown with gem stone embellishments. Her crystal box clutch and single pink cocktail ring made for a sophisticated evening ensemble.

While her makeup choices in the past include electric blue eye shadow in Nylon Magazine, this time her eyes were heavily lined and she balanced out the look with a glossy pout. The actress -- who lent her voice to the animated film "Rango" -- showed off a new, much lighter 'do.

Meanwhile, child actor Elle Fanning is younger than Breslin, but is just as savvy -- sartorially speaking.
