As we have previously learned, Jennifer Lopez is no throw-on-and-go beach babe. She remembers all the essentials, from jewelry to sarongs and fabulous shades. That's why we weren't surprised to find her poolside in Las Vegas, showing off her Moeva plunging-neckline suit with a metal buckle at the side. J Lo played up the hardware with crystal Fendi statement sunglasses ($505) and oversize hoop earrings. Her ensemble was glamorous and flattering, and it could be noticed from a distance. If that's your swim style, just read on to shop her suit and similar belted pieces.
