Teenie weenie yellow polka dot bikini! With the temperatures rising, summer can be a particularly uncomfortable season for expectant mothers. Hot and humid weather is tough for most people, but add a burgeoning belly to the mix and the day can quickly take a turn for the worse. Fortunately, clear skies and plenty of sunshine provide the perfect opportunity for mamas-to-be to head to the nearest beach (or pool!) and let gravity work its magic.

The hot weather looked like it was the last thing on Kendra Wilkinson‘s mind when she posed for a picture at the Pirate’s Booty Beach House! The former Girls Next Door star — who now headlines her own reality show, Kendra — was happy to show off the beginnings of a belly in her hot-pink bikini. Unlike Kendra’s barely there bump, a heavily pregnant Nicole Richie couldn’t hide hers! The proud mama — in a black bikini top matched with swim shorts — let the world catch a glimpse of her growing tummy when she visited the Malibu shores with boyfriend Joel Madden.

Although Kendra and Nicole didn’t mind baring their bellies, many designers often lean toward the two-piece tankini style for their maternity lines. While still offering the flexibility and comfort found in a bikini, the tankini also provides women with a bit more coverage. That isn’t to say traditional bikinis are unheard of for expectant mamas, but be prepared to put in extra effort in your shopping search!

Steal That Style: Kendra and Nicole’s Bikini Bellies with the two-piece suits below!

a pea in the pod’s Ruched Maternity Tankini

Breaking Bank: Looking to slim down the growing belly? Try a pea in the pod’s Ruched Maternity Tankini Swimsuit ($135). While the price may have you thinking twice before forking over the cash, the maternity line — known for its large celebrity fan base — is worth the splurge! The bikini bottoms sit very low, but the high back side offers plenty of coverage. Made with thick halter straps, the top will no doubt lend pregnant women plenty of support in those tiring months!

Brighten up a babymoon with Maternal America Maternity Jessie Flutter Tankini ($105)! The bold, beautiful fabric flows gently over the belly — ideal for women with sensitive skin — while at the same time boasting more than enough coverage of the bump. The halter-style top comes with adjustable straps for just the right fit, that can also be removed for added comfort.

Motherhood Maternity’s Keyhole Detail Maternity Tankini

Not Pinching Pennies: We are loving Motherhood Maternity’s Keyhole Detail Maternity Tankini ($40)! Not only does the floral design add the right touch of tropical flair, but the bikini bottoms pull up over the belly for extra support. Like most maternity two-piece suits, the bikini back sits up high to provide plenty of coverage to all the assets!

Ta-da! In search of a true maternity bikini? Prego Maternity Bikini ($60) fits the bill and then some. The traditional black bikini bottom sits under the belly button while the halter-style top comes complete with an adjustable tie for added support.

Liz Lange for Target’s Indie Dot Tankini

Bargain Buying: For women with large busts, pregnancy can pose a number of problems: In addition to finding maternity tops that give expectant mamas enough support, the added weight can often put a strain on the back. Fortunately, Liz Lange for Target’s Indie Dot Tankini ($15) knocks out two birds with one stone! The thick tankini straps are extra-wide to provide support where it is needed most.

Not pleased with any of these looks? Try mixing and matching your own bikini with Old Navy Maternity’s swimwear line. We think the Maternity Side-Tie Bikini Bottoms in Cabot Cove ($8) would look adorable with the Maternity Halter Tankini in Black ($10)!
