Swimwear
ShopBop.com
Known for its exhaustive mix of contemporary designers, shopbop.com carries a vast mix of swimsuits from Diane von Furstenberg, Milly, and Ella Moss, as well as exclusive styles from Fabucci and Brette Sandler. We love that models are always photographed from the front and back—so crucial when buying a bikini.
Nancy Meyer
A terrific source for hard-to-find, luxe European brands such as Domani, Eres Swimwear, La Perla, and Roberto Cavalli Swimwear. If your size or preferred color isn't available, they'll send you an e-mail update when new merchandise arrives so you can have the first pick.
Victoria's Secret
Victoria's Secret swimwear employs some of the same technology used in its super-popular lingerie collections (like Body by Victoria), so devotees of the brand can be confident that they're getting a fit they already love. The site also houses styles by tried-and-true designers such as Calvin Klein, DKNY, and Kenneth Cole Reaction.
J.Crew
This company is deservedly famous for its flirty-but-classic bikinis and one-pieces, and every style comes in a rainbow of colors and patterns—from muted florals to sweet seersucker stripes. We particularly like to mix and match the various options and sizes.
Malia Mills
Selling bikini tops and bottoms separately has become standard practice, but Malia Mills takes it to an even more size-friendly extreme by offering tops by cup size (30A to 40DD) and bottoms in sizes 2 through 16. The color palette is subdued: black, pewter, and cinnamon, as well as prints like an earthy-hued paisley. There's also a great sizing page that shows you precisely how to get the right measurements on your own.
Canyon Beachwear
With more than 50 brands to choose between, this retailer makes it shockingly easy to find what you're looking for. Not only can you search by brand, style, or color, you can also shop suits within a certain price range or by body type—like "full midsection" or "small hips"—a feature we haven't seen anywhere else.
Figleaves.com
Search separates or sets by color, price, or style. You'll discover more than 40 swim-centric brands here, many of them new or hard to find elsewhere, like Pour Moi?, Lepel, and Oskalily. There's a helpful product review section, so you can see what other customers have to say before you buy.
Swimspot.com
This site's unique Bikini Builder feature lets you mix and match tops and bottoms on a model to see exactly how your final style will look before you buy. Choose your favorites from the selection of suits by Nautica, Splendid, Athena, and many more.
