Promoting her new film Sin City: A Dame To Kill For, Jessica made sure she was fully prepped in the wardrobe department for both her appearance on US show 106 & Park and her evening out.
And we just love her day to night transformation!
You would have never have guessed Jessica was feeling a little under the weather for her TV appearance as she rocked up looking gorgeous in her skirt and blazer combo.
Flaunting her impressive figure, Jessica stunned wearing a plum midi skirt cinched in at the waist with a fitted black bustier top.
And despite looking in fabulous shape, a girl after our own heart Jessica actually revealed that she hates working out while chatting with the 106 & Park hosts.
She said: "I like how I feel after I work out, I hate doing it... I can give any excuse for not doing it. I do a little bit, but I need to do it with a friend and I need loud hiphop music!"
We hear you sister.
Jessica teamed her outfit with a tailored black blazer and dainty sandal heels as she clutched onto her gorgeous designer leopard print clutch from Saint Laurent.
A bag that beautiful is definitely worth recycling and Jessica did just that as she chose to give her a clutch a second outing that evening. Slipping into something a little slinkier and sexier, Jessica sure looked smokin' as she dolled up in her evening ensemble.
From girl next door to girl about town, Jessica sassed up her look in another skin tight teal bustier and a pair of high-waisted, navy flared trousers.
Keeping her hair as perfectly styled as it was earlier that day, Jessica glammed up her outfit with a gold torque necklace and a pair of metallic platform peep-toes on her feet to match.
Certified style icon? We definitely think so.
