Jennifer Lopez Ignores Halloween, Does Date Night in a Plunging Shimmery Lime Green Gown

While everyone else was dressing up for Halloween over the weekend (see: Paris Hilton as Britney Spears, a blonde Kendall Jenner channeling Marilyn Monroe), Jennifer Lopez ignored the holiday completely.

On Saturday, the multi-hyphenate attended friend Pia Miller's birthday party in Los Angeles alongside her husband Ben Affleck, dressed up as herself, which is always a fabulous choice. For the date night, which J. Lo documented on her Instagram page, she wore a slinky, sequined lime green gown featuring a plunging neckline, ruffled skirt, and an asymmetric slit. Coordinating strappy heels, a diamond tennis bracelet, and a metallic silver Cult Gaia clutch provided the finishing touches to her festive attire.

As for her glam, she stuck to her signatures of a bronzy contour, feathered lashes, and glossy lips, while her long caramel-colored hair was blown out in tousled waves with a side part.

J. Lo’s plus one for the evening, Affleck, dressed in a dark velvet two-piece suit with an unbuttoned white dress shirt underneath and a pair of brown loafers.

The stylish couple’s outing comes shortly after Lopez dropped a new capsule collection with the lingerie brand Intimissimi. The exclusive "This is Me...Now" collection is inspired by her upcoming album, which offers a bevy of intimates from lace bodysuits to long silk robes to garter sets.

"Lingerie is deeply intimate — it’s an embrace that empowers you to feel free and beautiful,” she shared in a statement. “It’s delicate, it’s soft yet reveals the confidence in yourself."
