The Mad Men actress, 36, wore a revealing, yet classy, black jumpsuit by Zuhair Murad 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 March 27, she shared a stunning selfie in her hotel room. "Objects in a @tomford mirror are prettier than they appear. Thanks @hungvanngo @rebekahforecast," she wrote.
