A tankini holds a unique place in the swimwear world. It’s a longer swim top designed to offer the easy comfort and midsection coverage many women love, while still letting you choose the bikini bottoms that suit your shape and style. It gives you that one-piece confidence without feeling restricted, and still keeps the fun of mixing different cuts, colours and levels of support. At its heart, a tankini is simply a tank-style swim top—yet today’s range of silhouettes, straps, fabrics and support features means it has well and truly carved out its own corner in modern swimwear.
What exactly is a tankini?
A tankini takes the simple idea of a tank top and reimagines it for the water. The result is a comfortable swim top that feels secure both in and out of the ocean or pool. Tankini tops come in all sorts of silhouettes—fitted or more relaxed, structured or soft, longer through the torso or cut a little shorter—so you can choose the level of coverage and support that feels right for you. And because the top isn’t attached to your swim bottoms, you avoid that familiar one-piece wrestling match in the change room, making it far easier to slip on and off after a long beach day.
Unlike a bikini top, a tankini offers extra length through the torso, closing the gap that some women prefer to keep covered. And unlike a one-piece, it lets you pair a top that works beautifully for your bust shape with bottoms that suit your hips. This flexibility makes tankinis a favourite for many body types, including long torsos, narrow waists and anyone who prefers a more personalised fit.
Why do tankini styles suit so many different shapes
Tankinis offer far more freedom than many people realise. For women with an inverted-triangle shape, features like wide straps or adjustable shoulder straps can help balance broader shoulders. Those with narrower hips might opt for boyleg or swim-short styles to create a little more harmony through the lower body. And if you have a long torso, a tankini lets you enjoy extra length without the pulling or distortion that can happen in a traditional one-piece.
Support is another reason tankinis are so loved. Underwired tankini designs offer reliable structure for fuller busts—often right up to a K cup—while shelf-bra styles provide a softer, more relaxed feel. Ruched tankini tops add gentle texture across the tummy and help shape a smooth, balanced silhouette. Halter or shoulder-style tankinis also give lovely lift without adding complexity.
Tankinis are also a favourite during pregnancy, as the top skims comfortably over a growing bump without the squeeze of a one-piece. And for active water sports or aqua aerobics, a well-fitted tankini provides both freedom and security, especially when paired with firm, supportive bikini bottoms.
Exploring different tankini styles
The variety keeps expanding, which means there is something for almost every personal taste.
Bandeau tankini
A bandeau tankini features a straight neckline, making it a great choice for avoiding tan lines while enjoying the sun. Our fitters love the Aria Botticelli Tankini Top for its comfortable, stay-put design and sleek look on a variety of body types.
Ruched or draped tankini
Ruched fronts or draped panels provide a forgiving finish across the tummy, enhancing curves while giving a smooth, balanced silhouette. Many ruched tankinis also feature adjustable side ties so you can customise the length and coverage to suit your body. Our fitters often point to the Hues Raphael Underwire Tankini as a favourite for shaping and comfort.
Underwire tankini
Underwire tankinis give structured support, shaping the bust while keeping you secure in the water. Ideal for fuller cup sizes, our team often recommends the Beach Waves Underwired Twist Front Tankini for reliable lift and a fit similar to a well-loved everyday bra.
Wirefree tankini
Wirefree tankinis are soft, relaxed, and gentle on the bust, making them perfect for those who prefer comfort without compromising shape or support. A great option is the Eco Essentials Cross Front Multifit Singlet Top, which pairs ease of movement with a flattering fit.
Mastectomy-friendly tankini
Tankinis designed with pockets for breast forms or slightly higher cuts provide security and a flattering shape for women post-mastectomy, combining style with thoughtful support. Our fitters highlight the Salta Blouson Mastectomy Tankini for a fit that’s both practical and stylish.
Cup-sized tankini
Cup-sized tankinis offer precise support in familiar bra sizing, so you can find a fit that feels secure and tailored to your bust. Our fitters often recommend the Iris Balconette Tankini Top for a reliable, personalised fit that feels just right.
Multifit tankini
Multifit tankinis are designed with a looser structure, allowing them to comfortably suit a wide range of body shapes and bust sizes. A great option is the Hues Delacroix Cross Front Tankini Top, perfect for women who want flexibility without compromising comfort or style.
Loose-fitting tankini
Loose or swing-style tankinis skim over the body for relaxed, breezy coverage, making them a favourite for casual beach days, family swimming, or those who prefer a non-clingy fit. A great choice here is the Eco Essentials Blouson Multifit Swim Tankini for easygoing style and comfort.
Mix and match possibilities
One of the great things about tankinis is the freedom to mix and match tops and bottoms to suit your body and style. You can pair a matching brief with your favourite tankini top, or try a plain or printed bottom for a fresh, personalised look. Tankinis are especially handy if you’re a different size on top and bottom, giving you the flexibility to combine support where you need it with style where you want it. Our fitters often suggest pairing a supportive tankini top with the Separates Shaping Super High Waist Bikini Bottoms for extra coverage and shaping, or a classic Signature Classic Brief for a timeless, versatile option.
How much coverage do tankinis provide?
Tankini coverage varies by design, giving you the freedom to choose what feels right for your body and comfort. Some tops offer the coverage of a one-piece, sitting low enough on the hips to meet your bottoms, while others feature adjustable elements—like side ties or ruched panels—so you can customise the length and fit for a sportier or more active style, such as the Spirit Plunge Underwired Tankini Top.
For women seeking tummy control or a smoother, balanced silhouette, a longer top paired with a firm brief is often the perfect solution. Those who prefer something lighter and easier for swimming or active water sports may enjoy a shorter tankini top that still feels secure and comfortable.
Care tips to keep your tankini in good condition
Tankini proper care is fairly simple. Rinse the entire suit in cool water after swimming to remove salt, sand and chlorine. Avoid wringing the fabric, and let it dry flat out of direct sunlight. This helps preserve elasticity and keeps colours bright. Treat an underwire tankini the same way you would treat a supportive bra, being gentle with the wiring and stitching. Never machine wash!
Why do so many women choose tankinis
Tankinis are a favourite for women who want a flexible middle ground between coverage and freedom. They provide the confidence of a longer top while still giving the feel of a two-piece, adapting beautifully to different body shapes, ages, and activity levels. Whether you’re lounging by the pool or swimming laps, tankinis offer comfort, ease, and practicality—especially for women with long torsos or anyone who dislikes the pull of a full one-piece.
Part of their appeal lies in the freedom to choose a top that fits the bust perfectly while pairing it with bottoms that suit the hips. Swimwear rarely offers this kind of thoughtful, body-friendly fit, making tankinis a go-to option for many.
