January Jones joined a host of celebrities who attended the CFDA/Vogue Fashion Fund Event held at the Chateau Marmont in LA, California, yesterday evening.

The ‘Mad Men’ actress wore a Rachel Zoe Resort 2013 jumpsuit.

Her chic blue printed look with a black collar, placket and cuffs was styled with a chain-accented leather belt from the Rachel Zoe Spring 2013 collection.

I love how comfortable this take on the PJ trend looks.

Black pumps and shades provided the finishing touches.
