Well, we're deep into the winter now, which means we'll be day-dreaming of bathing suits until it's socially acceptable to wear one and hit the pool. So, you best believe we're already thinking about swimwear. There’s really no better time to give that particular section of your wardrobe a much-needed update, so that when the summer months finally arrive, you're ready to pack your tote and hit the beach.

One-piece swimsuits continue to be a staple that's well worth having in your arsenal. Heck — they even tend to be a go-to for some of our favorite stars. (Remember Jennifer Lopez's white cutout option? Or Jennifer Garner's sweet, ruffled pick?)

It’s fairly easy to see why these fashion-forward celebs have been ditching itty-bitty bikinis in favor of a more modest silhouette. Not only are one-piece swimsuits extremely flattering on practically every body type, they also look super glamorous in poolside selfies. Plus, did we mention this versatile staple can double as a cute top when styled with skirts, shorts, and pants?
