The Ultimate Guide to Chic One-Piece Swimsuits
One-and-done poolside style starts here.
As summer approaches, it’s only natural to dream about days spent lazing in the sun by a glistening body of water. The only downside to this fantasy is the harsh reality of not having the best one-piece swimsuit for said occasion. If anyone understands the importance of having at least one good suit you can wear for the warmer season, it’s Shea Marie, the founder of the luxury swimwear label SAME. “Investing in a one-piece swimsuit is imperative, as it can become a key part of your summer wardrobe. It’s an incredibly versatile staple that can easily transition from the beach to dinner with pants or a skirt,” she told ELLE.com.
The versatility of this piece is what makes it perennially relevant, but that doesn’t negate the difficulties of shopping for the best one-piece swimsuits, especially online. From navigating inconsistent sizing to keeping up with current trends, there’s so much to consider. One golden rule that Marie swears by: Know what looks flattering on you. “One suit doesn’t fit all; that’s why we offer so many styles. Don’t be afraid to shop around because the right silhouette can change everything.”
Not sure where to shop? You’ve come to the right place. I’ve extensively researched the best one-piece swimsuits for women based on brand recognition, reviews, quality, versatility, trends, and price points. Trust that there’s a suit for you that will not only fit perfectly into your wardrobe but be the visual embodiment of an idyllic summer.
