Despite our best efforts and words of advice, (psst - there are other shades on the colour wheel, Chrissy) the 38-year-old Mad Men star plumped for another dress well within her sartorial comfort zone.
Regardless of her refusal to try out new things, we're willing to overlook it after surveying the photos of her latest red-carpet outing. Yes, she's wearing black AGAIN, but she does look pretty darn spectacular in a pleated LBD with a pretty Grecian flourish. The addition of cute black kitten heels, long dark earrings and a rather smug smile suggests that perhaps Christina did get our memo and is giving us two fingers in reply.
Loud and clear, Christina, loud and clear.
