Megan Hungerford, a fashion director and stylist whose client list includes Amazon Fashion, has advice to better ensure your satisfaction with your online swimsuit purchase. “Buy a safety suit from a well-known brand if you need a suit ASAP. It's fun to buy trendy suits from lesser-known brands online, but the quality and cut are oftentimes a bit of a crap shoot. So getting a backup from a brand that you know works for your body or at least is high quality is always recommended.” 

Read on for Byrdie’s favorite Amazon swimsuits that are guaranteed to make a splash this summer.

What to Look for When Buying Swimsuits on Amazon


It’s ideal to invest in a high-quality material that won’t start to “sag” or “droop” over time as some of the cheaper fabrics do after a few wears and washes. You’ll want a swimsuit sturdy and thick enough to maintain its integrity. Look for a lined swimsuit, as anything unlined is less likely to hold up and may look flimsy. Elastane (also known as spandex) will provide plenty of stretch and security, ideal for one-pieces. Nylon is commonly seen in swimsuit materials for its soft and lightweight properties. Look for blends that combine materials to get multiple benefits.

“Quality over quantity is true, and the most sustainable way to purchase bathing suits, which are inherently a non-biodegradable material,” Donahue explains. That’s why we’re fans of sustainable brands like Vitamin A and Maaji, whose suits are made out of recycled materials and plant-based fibers. The investment correlates with the longevity and durability of your suit and the impact on the environment. 

  • Can you return swimsuits on Amazon?

    Yes, as long as you haven’t worn them, you can return a majority of Amazon swimsuits for free. Just make sure to leave the liner on when trying them on. Some swimsuits also offer a Prime Before You Buy feature, which we suggest taking advantage of. With your Prime membership, you choose the items you want to try on, get them shipped to you at no cost, and only pay for what you keep. You can return the rest for free with a prepaid shipping label.

  • How do you measure swimsuit size?

    Most swimsuits on Amazon have a size guide you can refer to. Measure your bust, waist, and hips to get the most accurate reading of your swimsuit size. Donahue recommends taking “a look at the reviews, as they are the most accurate representation of how the suits will look on all different body types.” For extra assurance you’ll be comfortable with the fit, look for a suit with adjustable straps.

  • Can you wash swimsuits in the washing machine?

    Some suits can hold up fine in the washing machine (always use cold water though!), but hand-washing is generally recommended. This ensures your suit will maintain its shape and quality. Amahlia Stevens, founder of Vitamin A, advises using an “all-natural biodegradable soap and to rinse in cold water after each wear” as well as hang-drying every time. This extra care may take time but it's worth it because “​​taking care of your wardrobe is one small step toward being a conscious consumer,” she says.

  • How do you style a swimsuit into an outfit?

    One-pieces swimsuits have a perfect double-duty function as a bodysuit. “Throw on a pair of ‘90s mom jeans and an of-the-season PVC kitten heel to complete the perfect beach-to-bar look,” Hungerford says. “Layering a classic white button-front shirt over a modern metallic bikini top is the perfect way to elevate the seasonless summer essential with a little modern edge. Leave the top three or four buttons unbuttoned so that metallic can shine.”
