The Mad Men star channeled her inner Joan Harris at the Tracy Paul dinner for Uno de 50 in West Hollywood on Thursday night.
Christina made her comeback in a beautiful sixties-inspired black cape that was worn over a simple black sheath.
Not only was it her outerwear that made her look so chic and elegant, but it was her accessories, too!
Satin pumps with her deep green, velvet clutch and matching hat were the ultimate touches to polish off the redheaded beauty's retro look.
Keep this up and you'll get your fashion streak back in no time!
