A busy press tour comes with many outfits, and with only a few days until the release of "Marry Me," [1] Jennifer Lopez [2] has sported one stylish look after another. While performing the film's titular track [3] on "The Tonight Show Starring Jimmy Fallon [4]," Lopez wore a white outfit consisting of an extremely cropped leather blazer [5] over a bralette [6] and a 2000s-inspired long, low-rise skirt [7] with hip cutouts.

Styled by her go-to stylists Rob Zangardi and Mariel Haenn, the custom Grace Ling ensemble accentuated her toned abs [8] as she sang alongside her costar Maluma [9], who wore a bright sage green suit. Though Lopez's outfit was undoubtedly eye-catching from the front, she revealed the even sexier back during her performance: an exposed thong with a shiny sculptural square plate. She kept the same accessories — earrings and a gold cuff from Tiffany & Co — from her earlier chat with Fallon, which she paired with a sleek red Norma Kamali slip dress.

If the all-white outfit looks familiar, it's because the actor-singer posed in the exact jacket-skirt combo in black last week, in a photo shoot for "The New York Times." [10] Ahead, watch J Lo and Maluma's full performance, and catch a closer look at their fab style.
