A high-waisted bikini bottom is the secret to achieving an hourglass look on the beach. The contrast piping makes the mega-watt colors on this swimsuit pop from a mile away, so you're sure to draw major attention on your vacation.

It's hard enough to shop for maternity clothing, let alone swimsuits. Thankfully, Summer Mae thought out every detail when designing this one-piece for mommas to be. First and foremost, you'll find so many reviews raving about how comfortable this swimsuit is and how it has room for a growing bump.

Holds everything in well and the zipper surprisingly stays put well, doesn’t slide down even if not pulled all the way up. The arms give excellent sun protection. My only issue was it was a bit loose on my narrow hips. The top part fit perfectly. Definitely want to buy in other colors."
The top of this one-piece is so cute, we would wear it as a bodysuit with our favorite denim shorts. It does run small, though, so make sure to size up. It has over 17,000 five-star reviews, and several claim that going up one size is perfect.

As adorable as the front of this one-piece is, the back is even more so. It features ruffle straps, a cut-out, and a lace-up detail to allow for a better fit.

In case you're on the hunt for something more athletic or modest for the beach, Leave it to Speedo to get you covered —literally.

I wash it, sometimes it gets thrown in the dryer on accident, but it is still holding together."

When you have a big bust, swimsuit shopping can be a nightmare. But a few minor details can make all of the difference between a well-supported top and a wardrobe malfunction. Take this top from Body Glove for example. Specially made for big busts, it has underwire and an adjustable tie-back for the best, most supported fit possible.
Color(s): 12 colors and prints

Composition: 85 percent nylon, 15 percent spandex
What We Love: Adjustable tie-back; has removable pads; has underwire for support and lift.
What We Don't: Over $50; bottoms sold separately.
Customer Review: I have this top in three colors because the fit is so great. I have a small band size but full breasts (30DD) so the fact that it ties such that the band is adjustable is what makes it so great. The cups also have good coverage.
On the opposite end of the spectrum are these bikini bottoms. In between thong and full-coverage, these bottoms offer the perfect amount of coverage for those who like to show a little extra skin, but won't have you feeling embarrassed to be around kids. Reviews say they are comfortable and won't ride up while walking—the true test of a great pair of cheeky bikini bottoms.
Color(s): 29 colors and prints
Size Range: Sizes S-XXL
Composition: 80 percent polyamide, 20 percent spandex
What We Love: Comfortable.

Customer Review: "This looks nicer than I anticipated. The material feels expensive. Very high quality. It fits great, cheeky, but without riding up. I honestly rarely buy clothes from Amazon, but after looking for something similar for a while, I broke down and did it. I'm glad I did. I would absolutely buy this again!"
Unfortunately, a lot of the bikinis you come across on Amazon come in sets, so your best bet for a custom fit is to order separates, especially if you prefer more coverage. These bottoms have you covered in every sense with a high-waisted fit, ruched stomach detail, and full rear coverage. With over 20 colors and prints to choose from, you're bound to find a match for your go-to top.
Color(s): 18 colors and prints
Size Range: Sizes XXS-28 Plus
Composition: 82 percent nylon, 18 percent spandex.
What We Love: Offer high-coverage; high-waisted bottoms provide tummy support.
What We Don't: Top sold separately.

Tankinis on Amazon
With all of the strings and ties in traditional bikini tops, wardrobe mishaps can and likely will happen eventually. This top, however, forgoes all of the tricky ties so you feel supported and secure all day long. It fits just like a sports bra with sewn-in padding that won't bulge or move around while you're wearing it. The fabric is also similar to athleticwear with a breathable, stretchy, quick-drying feel. Grab the matching boy shorts and you've got a comfortable, supportive bikini.
Color(s): 24 colors
Size Range: Sizes XS-XL
Composition: 78 percent polyamide, 22 percent elastane
What We Love: Comfortable; breathable; supportive.
What We Don't: Bottoms are sold separately.

With all of the look of a swim dress but with the convenience of a two-piece, this tankini combines the best of both worlds. Ruched detailing along the bust creates a flattering effect, while the built-in push-up bra adds extra support and shape. Lots of reviews point out this suit's great fit, adding that it won't swallow you up.
Color(s): 29 colors and prints
Size Range: Sizes XXS-24 Plus
Composition: 82% nylon, 18% spandex
What We Love: Has adjustable shoulder straps; top has removable pads.

Not everyone likes to wear teeny-tiny bikinis, and that's okay! For those who aren't keen on cheekiness, this tankini with athletic high-waisted shorts is a great option. The shorts will keep you covered and supported, while details on the top, like the strappy back and drawstrings, add a feminine feel.
Color(s): 34 colors and prints
