Regardless of what month the calendar reads, stars at this week's Santa Barbara Film Festival were as pretty as spring flowers in their floral frocks.

Sandra Bullock even accessorized her L'Wren Scott sheath with a fistful of buds.
And "Atonement" and "Lovely Bones" actress Carey Mulligan's carnation pink Spring 2010 Prada number is as sweet as the floral print on Saoirse Ronan's silk design.
