She loves the colour blue, and this printed gown was an infinitely better attempt than Katy Perry's Smurfs 2 promotional style. Phew.
The singer was actually looking rather lovely at the 2013 Delete Blood Cancer Gala at Cipriani Wall Street, New York, in her fishtail Vera Wang gown, Jimmy Choo heels and Judith Leiber clutch.
She wore her hair up in an elegant 'do, and grinned as she posed for pics with the dress' designer herself, Ms Wang, who was wearing a rather daring number that featured a plunging cutout waist.
What do you think of Katy's style? Too blue or true blue?
