Jennifer Lopez’s St. Agni Top Has the Biggest Back Cutout You’ve Ever Seen

Jennifer Lopez constantly elevates business-casual style with surprising fashion twists. Stepping out at an office building in Los Angeles, the star looked effortlessly chic in a minimalist white outfit. While her look seemed understated from the front, it turned heads from behind with a dramatic open back. She proved once again that clean tailoring and daring cutouts create the ultimate summer combination.

Jennifer Lopez bares her back in St. Agni top with massive back cutout in LA

Jennifer Lopez made a sleek appearance in Los Angeles while visiting an office building. As she stepped out of her SUV, paparazzi caught sight of her elevated monochrome street style.

The centerpiece of her look was a crisp white Racerback Top by Australian label St. Agni. From the front, the piece offered a sophisticated high halter neck and structured bust darts. However, as she walked, the top revealed a massive open-back cutout that dipped dangerously low past her waistline. A delicate thin tie fastening at her lower back held the dramatic open silhouette together.

J.Lo balanced the daring reveal of the backless top with loose, menswear-inspired tailoring. She paired the top with relaxed, low-rise wide-leg trousers featuring subtle pinstripes. The fluid pants draped gracefully over her platform heels as she walked inside. The full outfit showed how high fashion can feel relaxed and powerful at the same time.

She carried a black leather Dior Groove 25 handbag in one hand and held a pair of oversized aviator sunglasses. Her hair was pulled back into a sleek, high ponytail that kept her exposed back completely visible. For her glam, she chose sculpted bronzed skin, glowing highlighter, and a glossy nude lip.

The look works because the proportions do the styling work: a fitted, high-neck top provides structure from the front, while the open back introduces the unexpected reveal. The relaxed wide-leg trousers then offset the fitted upper half, giving the outfit a deliberately loose-versus-revealing contrast.

Amal Clooney Wore Optical Illusion Jeans Cosigned by Jennifer Lopez—Fall-Ready Styles Start at $44

My list of must-try jean trends for 2026 is growing; it currently includes all the silhouettes one denim expert revealed to me as the must-watch of the year (save for baggy jeans, because I’ve been wearing those for years). That said, one style that didn’t land on said aforementioned list, but is clearly due for big, big things this year, is flare jeans. With a growing list of celebrity fans that includes Meghan Markle, Jennifer Lopez, Reese Witherspoon, Cindy Crawford, Kendrick Lamar (you know that moment), and, of course, Amal Clooney, there’s no denying the retro denim style that was popular in the early aughts is back—and bigger than ever.

The fact that Clooney wore flared jeans is noteworthy in and of itself. The human rights lawyer is known for her refined dressing approach, regularly opting for billowy trousers, trendy boho blouses, and comfy sweater dresses—all staples that read elegant and timeless. So, when I spotted her earlier this year in the laid-back blues while out to dinner with hubby George Clooney, I knew I had to write about it. Of course, the fact that she wore flare jeans, the style countless celebs have worn the last few weeks, is noteworthy, too, as it further cements the style’s ‘It’ status for 2026.
