Bubblegum pink is not only one of the most popular color trends in the ready-to-wear space but the swimwear space as well. This very saturated, very bold hue is that little burst of joy we've been searching for everywhere this year.

Flip It & Reverse It

What definitely originated as a DIY situation has now turned into one of the most talked-about bikini trends of 2021. Instead of taking a regular triangle bikini, turning it upside down, and tying the top around your back, swimsuit brands are now just selling tops that look like you did that, ensuring a fit that's a tad more secure. 

Really Retro Florals

This year, florals finally feel fresh again thanks to the retro take we've been seeing quite a of lot lately. Taking influence from both the '80s and '90s, these nostalgic prints are exactly what your swimwear collection has been missing. 

Mermaid Moments

This one feels a tad more whimsical than you might be used to, but if Versace is doing it, then it must be cool. Bikinis adorned with seashells, underwater landscapes, and mermaid-inspired tops are the new swimwear theme that's been hard to ignore, so enjoy the shopping selection of my favorites thus far. 

Gorgeous Glitter

Glitter, glitter, and more glitter. Choosing just four bikinis to shop out in this trend section was one of the hardest things I've had to do in a long time. In other words, there is no shortage of glimmering glittering swimsuits this year, so I suggest you get your hands on your favorite take on the trend ASAP. 

Terry Times

Honestly, what's a trend roundup these days without a subtle nod to the early 2000s? This newly reinstalled Y2K vibe is officially a lifestyle, and that means your bikinis are affected too, starting with the terrycloth trend. You probably never thought you'd see this trend rise again, but alas, it's emerged and it's pretty damn cute if I do say so myself.

This might not feel like the "newest" trend on the block, but now that we've called it out, you won't be able to stop seeing it. Animal prints are always a safe bet when it comes to swimwear, but this summer, zebra print is where it's at, period. 

Shorts Stories

Last but not least, swim shorts. Vintage-inspired tiny shorts are the new barely-there thong, and honestly, thank goodness?
