Gossip Girl star Blake, 26, chose a gorgeous floor-length floral frock by designer Oscar De La Renta for a fundraising event for Parkinson's disease, held in New York at the weekend.
In fact, the US star looked like the perfect English Rose in the demure, embroidered gown.
The actress showed off her slim figure in the structured dress, which had an elegant off-the-shoulder neckline and full skirt, emphasising Blake's slim waist.
And Blake, who is married to Hollywood heart throb Ryan Reynolds, continued the floral theme with her fresh-faced make-up, choosing pink cheeks and lips, and even a rosy hue on her eyelids.
The glowing star wore her blonde tresses in loose waves that tumbled over her shoulders, and added a double strand of pink beads to accentuate her decolletage.
Perfectly polished but bare nails and nude pointed courts completed her summery look.
