Jennifer Lopez Paired a Turtleneck, High-Slit Dress with the Tallest Stiletto Boots

Jennifer Lopez, known for her sexy dressing, just wore the perfect autumnal outfit that screamed "hot girl fall" in the most subtle way.

On Sunday, the Second Act star joined her boyfriend Ben Affleck at a Los Angeles screening of his new film The Tender Bar at the Pacific Design Center in West Hollywood. For the occasion, the actress wore a super chic, all-black outfit, which included a long-sleeve fitted turtleneck dress that had a thigh-high leg slit and a flouncy hem. The dress's opening revealed a pair of badass knee-high stiletto boots that were complemented by a matching Valentino handbag, oversized aviator sunglasses, and hoop earrings.

J.Lo arrived hand-in-hand with her man Affleck, who paired a plain white tee with a tan suede jacket and dark wash jeans. He wore brown dress boots and carried an iced coffee in hand (no, not his usual Dunkin' Donuts order).

The actor's director of the new film, George Clooney, was also seen at the event with his wife and human rights lawyer Amal who wore a gorgeous cutout gown. According to Deadline, the coming-of-age film follows a young boy growing up in Long Island who is seeking "father figures among the patrons at his uncle Charlie's (Affleck) bar." It will be available for streaming on Amazon Prime Video on January 7.
