Setting our sight on seasons ahead is what we do best at Marie Claire —and that means getting a jump on the spring/summer 2021 trends. We may not yet know what summer will hold, but finding new ways to stay cute and cool in your yard or atop your roof will likely come down to a few things: grabbing a swimsuit, some shades, and a can-do attitude. While we hope that the warm weather season is filled with beach trips and poolside BBQs, we know that fantasizing about what kind of swimsuits we'll be summering in is basically half the fun. Ahead, we've got the swim trends you'll be eager to weave into your swimwear arsenal in the months ahead.

1. The Little Black Bikini

Investing in a sophisticated black two-piece is the beach and poolside equivalent of a little black dress. This spring, designers are presenting even more options for the black bikini, with a major focus on a high-waisted silhouette.

Designers are keeping 2021 light and bright with ethereal ruffle necklines and flounce waist detailing that injects femininity into swimwear in just about every style and print.

Trade out subtle tones for animal motifs that will once again take the lead this swimwear season. Essentially a "neutral" print, you can seamlessly pair cheetah and tiger prints with printed caftans and bright warm-weather accessories.

There will be no shortage of sport-forward swim this year. Whether you plan to dive into the lap pool or just prefer a straight-shooting suit sans ruffles and strings, designers will have a wide range of athletic-inspired options that don't skimp on the style factor.

When it comes to swimwear, less is not always more. Case in point: designers' steadfast devotion to high-waisted swim sets. As in years past, expect to find an array of high-waisted options, from slightly retro briefs to high-cut, high-waisted '90s styles.
