Womens’ plus size tankini tops

Swimwear challenges for plus-size women

Plus-size swimwear includes sizes XL–3XL (14–24). Plus-size women run into these common swimwear issues:

Shoulder straps cut into the skin, causing discomfort throughout the day.
Small cups create unflattering bust spillage.
Inadequate bust support leads to poor shaping.
Bottoms shift position during water activities.
Tops slip down during active movement.
Low-quality materials irritate the inner thighs.
See-through fabric when swimming.
Rigid underwires press uncomfortably against the skin.
Elastic loses shape after a few washes.

SwimZip's plus-size swimsuit collection uses premium fabrics, strong support structures, and figure-flattering cuts that stay in place.

Our stylish plus-size tankinis

Our plus-size tankini tops pair with many swim bottoms to express your personal style. Here are features that make our tankini tops stand out:

Sun-smart protection: UPF 50+ fabric blocks 98% of UVA and UVB rays. Our nylon/spandex fabric resists chlorine, dries fast, and maintains shape through multiple swims.
Perfect fit: Our 4-way stretch fabric moves with your body. Adjustable straps, a built-in bra, and removable cups create personalized support.
Stylish details: A high neckline protects your chest from sun damage. Front ruching sculpts your silhouette, and a void cut-out detail adds flair to the back.

From floral prints to solid colors, you will find plenty of styles to match your preferences.

What is a tankini?

A tankini is a clever mix of a tank top and a bikini bottom that gives you the best of both swim worlds. The longer top extends to the waist and provides more coverage than a bikini top but lets you show some skin if you prefer.

The bottoms come in multiple cuts, from brief styles to shorts to skirts. Because tankinis come in two pieces, you can mix and match different sizes for the top and bottom parts to fit your body type. Plus, tankinis make bathroom breaks a breeze compared to a wet one-piece.

How do I choose the right plus-size tankini top?

For the best fit, pick your usual bra size. The fabric should lie flat without pulling, and straps must stay secure during movement. With a properly fitted tankini top, you'll step into summer with confidence.

Pick a style that matches your body type. Tankinis are especially flattering for the following body types:

Hourglass shapes stand out in empire waist styles.
Rectangle shapes shine in tops with built-in shaping.
A-shape figures look stunning in tops with ruching across the chest.
Apple shapes glow in pieces with straight, flowing lines.

Choose support that enhances your confidence. Light support includes a built-in shelf bra and medium support offers removable cups with wide straps. For full support, look for features such as underwire options with adjustable bands for active swimming.

Length options let you control coverage. Mid-torso styles show a flash of skin, full coverage extends past the waist, and tunic lengths offer maximum coverage. In our selection of tankini tops, you will find classic scoop necks, high-fitted necks, one-shoulder crops, and flattering a-line designs.

How can I style my plus-size tankini tops?

You can style plus-size tankini tops in so many fun, fashionable ways:

Pair a black tankini top with plus-size swim shorts for a sporty look with extra coverage. A black tankini is a classic choice that never goes out of style.

For a chic, monochromatic look, match a white tankini top with a white swim skirt. A white tankini pops against sun-kissed skin.
Pair your favorite tankini top with high-waist swim bottoms for a retro-inspired silhouette that highlights your curves. Look for bottoms with tummy control panels for an extra boost of confidence.
Accessorize with a floppy sun hat, strappy sandals, oversized sunglasses, and colorful jewelry to show off your personal style. Your tankini top is a versatile foundation piece.

With so many stylish designs and prints available, you'll have a blast building resort-ready outfits around your plus-size tankini tops. Whether you prefer a relaxed fit or more structured support, there's a tankini to match your unique vibe.

Plus-size tankinis FAQ

Do you wear a bra under a tankini?

Most tankinis have a built-in shelf bra or removable cups, so you don't need to wear a separate bra underneath. But, if you prefer more support, you can wear your favorite sports bra or swim bra under your tankini top.

How tight should a tankini be?

Your tankini should fit snugly but not feel restrictive. The fabric should skim your curves without gaps or pulls. Adjust the straps for a comfortable, secure fit that stays in place when you move. If the tankini rides up or slips down, try a different size.

Can I wear biker shorts for swimming?

You can wear biker shorts for swimming if they're made from swimwear material, such as nylon or polyester blends. Look for biker shorts with a built-in liner and quick-drying, chlorine-resistant fabric. Avoid cotton biker shorts, as they will become heavy and take a long time to dry.

Do you offer plus-size swim dresses?

We offer swim dresses in sizes XS to 3X. Our swim dresses feature built-in shorts for added coverage and comfort. Whether you play beach volleyball or build sandcastles with your kids, our swim dresses protect you from harmful UV rays and make you feel comfortable.

Do you offer modest plus-size bathing suits?

We offer modest plus-size bathing suits for women and girls. In our wide selection of gorgeous swimsuits, you’ll find plenty of options to suit your modest style.
