January Jones was spotted attending a private party in Bel Air, California on Sunday afternoon.

The ‘Mad Men’ actress wore a pretty blue dress designed by one of her favourite off-duty brands; Madewell.

Her ‘Gatehouse’ silky long-sleeve dress with a quirky-yet-feminine tulip hem was worn by Solange Knowles in the ‘Mix Well. Madewell’ Fall 2012 ad campaign.

January styled her frock with nude ballet flats, a quilted bag, gold hooped earrings, a gold bracelet and shades.
