Swim season is upon us, and plus size swimwear has never had such style variety until now. No matter what type of swimwear shopper you are, there's something for you on this list. While everyone has a different body type and their own feelings on what they'd like to reveal, take a chance on something new this swim season. Inclusive swimwear is on the rise, and there's so much more to choose from than the simple designs or plain black of the past.

If you're looking for plus size swimwear, begin with your dress size to start finding your perfect fit. However, each brand will vary and you may want to size up or down depending on each brand's size chart and swimwear description.

Cupshe Ruffle Plunge V Neck Plus Size One Piece Swimsuit takes the top spot for its deep v design and illusion waist that toes the line between bikini and one-piece. With a wide size range and pretty detailing, it offers the wearer something sexy and stylish, while remaining comfortable.

Read on for a list of the best plus size swimsuits available in sizes 3X or larger.

What's great about a deep V plus size swimsuit is that it makes for a sweet bodysuit, too. Cupshe has a full line of plus size swimsuits inclusive of this Ruffle Plunge V Neck Plus Size Swimsuit. With some flare on the shoulders and a mesh see-through midriff, the swimsuit gives off the illusion of a two-piece if bikinis aren't your jam.

What We Love: The two color options make them look like totally different pieces.
What We Don't Love: The price is a bit steep for a one-piece swimsuit.

Once upon a time, one-shoulder swimsuits would be terrifying. However, this little number from Eloquii — that also comes in all black — is a marbled marvel for swim season. The thick one shoulder offers enough support for bigger busts. Plus, the bust holds a lining with removable foam cups and an inner shell bra for support—no one but you will know it's there.

Fabric: 80% Nylon, 20% Spandex | Size Range: 14 - 28 | Colors: 2

What We Love: It's simple, stylish and comfortable.
What We Don't Love: The cups aren't fit to bra sizes.

The colorblocking on this one-piece is why it remains one of Summersalt's best-selling swimsuits. Simple, cute and perfect to get you to the beach and back home with its colorful hues. Offered in four other colorblocked options with built-in cups and adjustable straps, you can sport this with a pair of jeans and no one would even peep it as water-resistant.

Fabric: 78% recycled polyamide, 22% elastane | Size Range: 2-22 | Colors: 4

What We Love: The wide size range and mesh detailing
What We Don't Love: It's sustainable, so it doesn't have the same elasticity as other supportive swimwear designs.

NoMads prides itself on offering a wide range of sizes in its swimwear offerings, while staying committed to using sustainable fabrics. The Bay Swimsuit tricks the eye with its mesh colorblocking. Made with regenerated nylon and elastane, the brand offers medium impact support for the bust.

Best Shorts: Woman Within Chlorine Resistant Long Bike Short Swim Bottom

What We Love: The fact that these bike shorts are knee-length.
What We Don't Love: These shorts are more mid-waist than high-waisted.

For some, shorts are the best swimwear solution—whether you want more coverage or to avoid chafing out of the water. These Woman Within Chlorine Resistant Bike Short Swim Bottoms will be your go-to, because sometimes, a basic pair of black shorts and tankini is all a person needs.

Fabric: 80% Nylon, 20% Spandex | Size Range: 8-26 | Colors: 2

Best in Black: Meet.Curve Black Crossover Lady Vintage One Piece Swimsuit

What We Love: It's stylish enough to wear as a bodysuit.
What We Don't Love: The swimsuit could have more butt coverage.

Retailers have gotten the memo: not every plus size black swimsuit needs to be basic. In fact, these days swim is expanding in more ways than just sizing. Meet.Curve offers a plethora of stylish and inclusive swimwear pieces. However, the cross front detail that transforms into a square back is too cute to ignore. With a peep of skin in the middle, this swimsuit is equal parts elegant and sexy with a touch of vintage vibes.

What We Love: The bra cup sizing is great for bigger busts.
What We Don't Love: The criss-cross design can look a bit dated.

The fit on this is great for busts large or small with its underwire bra with sewn-in soft cups that hug you like a glove.

What We Love: The overall design and color variety.
What We Don't Love: There's not a lot of bust support, if your size runs bigger on top.

Monokinis have been on the rise as a middle ground between bikinis and one-pieces. Good American's stylish monokini comes in a variety of summery shades, and is made from a stretchy fabric that moves with you. Plus, it has a high-waisted bottom clasped by two cute side rings.

What We Love: The thick bra straps on these won't have you worried about a potential slip.
What We Don't Love: It's very simple and geared more for training than style.

Adidas doesn't play when it comes to giving customers quality activewear. Thankfully, the same can be said of its plus size swim line.

What to Keep in Mind

Fabric

Swimsuit fabric plays a huge role in comfort and fit. It needs to be stretchy and conform to the body and dry fast, yet maintain its color and shape in the water. A popular combo for swimsuits is a polyester and elastane blend. Elastane is super stretchy, better known by its brand names of Spandex or Lycra, and polyester is durable, and also colorfast and resistant to chlorine, so swimsuits stay vibrant. Nylon is another popular choice, because of its strength, however, it can pill over time.

Fit

When shopping for swimwear online, bear in mind what or how much you're comfortable with showing. Thicker straps can offer more support for larger busts and so can a swim top that has underwire or deep cups to keep you secure. Bikinis and one-pieces aren't the only choices. If you're looking for more coverage, swim dresses, shorts, or long sleeve designs may be an option for you as well.

Your Questions, Answered

How do I know what the right size is for me?

Start with your dress size to get an understanding of the size range you're in. This can also help you to hone in on the stores you're targeting, since, unfortunately, not all stores carry past a 3X (and some haven't even expanded to that range yet). To be even more accurate, use a measuring tape to record the size of your bust, waist, and hips and compare it against the brand's sizing chart. The size that is closest to your measurements is usually your true-to-size option. Not to mention, a plethora of tops and bottoms are sold as separates, which may be crucial if your sizing varies widely from the one-piece options or sets that don't sell separately.

Is it better to size up or down in swimwear?

Choosing to size up or down can depend on each brand's size guide and the swimsuit style you're after. If compression is what you hope to nab in your swimwear, you may want to consider sizing down. Some swimwear brands will note if their models have sized down from their dress size for a better fit. Reading reviews can also help you to understand the comfort level of the swimsuits and whether adjusting from your typical size is necessary.
