Hailey Bieber’s Best Bikini Moments Through the Years

Hailey Bieber has a signature style all her own, and it’s especially evident with her seaside fashion.

A prolific model, a proud mother and a beauty mogul—having founded the mega-popular cosmetics brand Rhode, which she sold to e.l.f. Beauty last May in an impressive $1 billion deal—Bieber has long been a style star to watch. Whether she's on the cover of a major magazine, walking the red carpet or supporting her husband, Justin Bieber, at Coachella 2026, the model’s wardrobe always leans chic, modern and timeless.

And to the delight of fashion fans around the world—56.7 million of whom follow her on Instagram—Bieber also often shares her fashion finds on social media. This includes her vacation wardrobe, as well, which has naturally caught our eye over the years (we are SI Swimsuit, after all!).

With that in mind, we’re taking a look back at just a handful of Bieber’s best bikini, swimwear and seaside style moments that you can totally use to inspire your summertime wardrobe!

Hailey Bieber’s best bikini moments

As seen on her Instagram account, Bieber is no stranger to a classic string bikini, whether it’s crafted in a solid shade or a fun and funky pattern. Typically opting for traditional, triangle-shaped tops and flirty, high-cut bottoms, the model always turns up the heat on her two-pieces by adding accessories, including hats, body jewelry and, of course, plenty of Rhode products. Check out a few examples of this below!

Still, the model doesn’t rock swimwear only while she’s on vacation! She’s also been seen sporting a suit or two on the covers of major magazines. Interestingly enough, fashion teams tend to opt for unique one-pieces when styling the star for the front page, with monokinis always making the cover girl stand out.
