Bikinis tend to get all the hype, but don’t underestimate the power of a great one-piece swimsuit. On top of offering additional coverage when you want it, the best silhouettes are also incredibly stylish and flattering. Better yet, some even double as bodysuits, so you can save space in your suitcase on your next vacation.
If you’re looking to refresh your one-piece rotation ahead of summer, Amazon has so many stellar options that you can unbox (and promptly pack) in just a few days. From coveted designer and name-brand pieces to affordable hidden gems offered in a wide range of sizes, the e-retailer is home to pages upon pages of one-pieces to suit practically any style, body, or budget. Whether you’re looking for a trendy plus-size one-piece or a timeless maillot ideal for small busts, you’re bound to find it on Amazon.
To help narrow down your search, I culled the e-tailer’s massive inventory to bring you this meticulously curated list. I included a range of looks from brands I know and love as well as some highly-reviewed options from smaller labels for whatever you have planned this season. Seeking something minimal and classic for lounging poolside with a new book? Norma Kamali’s strapless option is a great pick. Or, if you often spend your beach days playing volleyball and swimming, RVCA’s racerback one-piece or Onia’s high-neck design will make a fabulous addition to your lineup.
