If you ever want to know what designer bags are trending, just look at some of the most stylish celebrities—think Jennifer Lopez, supermodels, and basically anyone else that has a good stylist. Chances are, these celebrities will be carrying the latest highly coveted It bag. Currently, the bag on many stylish celebrities' arms is the Valentino One Stud Bag.

The pretty bag features a luxurious chain strap and a flap secured by a single gold pyramid stud (there's also a top-handle crossbody iteration). It's one of those bags that's instantly recognizable as Valentino, given that studs have been one of its signatures for years.

The bag is a recent release from the brand, and we've seen everyone from Meghan Markle to Jennifer Lopez to Anne Hathaway toting it around as of late. If you're in the market for an investment-worthy designer bag, the One Stud is a great option, as it can work for day or night and it comes in a wide variety of colors and sizes (with the Medium size seemingly being the most popular among celebs).
