Oh, Betty! January Jones turned up the heat as she left her undergarments at home during an appearance on "The Tonight Show" with Jimmy Fallon on Friday.
The "Mad Men" actress, 36, wore a revealing, yet classy, black jumpsuit for the visit with matching heels. The plunging neckline ensemble showed off major skin with cut-out detail placed strategically down her leg. To top it off, Jones kept her makeup simple with a touch of light blue color.
Earlier in the day, Jones stepped up her fashion game once again in an '80s-inspired look. The "X-Men" star was photographed outside her hotel in NYC wearing an edgy white blazer with a black t-shirt and J Brand "Genevieve" jeans. She completed the look with a bold red lip and bee-hive hairstyle.
Jones and her fellow AMC costars are currently in NYC for the show's upfront presentation. On Thursday, she shared a stunning selfie in her hotel room. "Objects in a @tomford mirror are prettier than they appear. Thanks @hungvanngo @rebekahforecast," she wrote.
