Finding the best swimsuit for your body type is less about rules and more about knowing what each detail does. Every body is a beach body, and the right swimsuit is simply the one that makes you feel confident, comfortable and ready to enjoy the sun. This guide explains how high-cut legs, ruching, underwire and other details work, so you can choose with ease, whatever your shape or bust size.
Swimsuits for body types: a simpler way to think about fit
Traditional body-type guides can feel restrictive. Instead of thinking about what to disguise, think about what you love and want to show off. A swimsuit is a celebration, not a correction.
Start with what you want to highlight
Do you love your legs? Choose a high-cut leg. Want to draw the eye to your shoulders and collarbones? Try a halter neck or a scoop neckline. Want to celebrate your curves? A plunge or a ruched bust frames them beautifully. Start with the feature you love most, and choose the details that highlight it.
Swimsuit details and what they do
High-cut legs
A high-cut leg sits higher on the hip, which visually lengthens the legs and creates a flattering, elongated line. It is one of the most universally flattering details in swimwear, and it suits every height. The Sienna Scoop Neck High-Cut Swimsuit in Chocolate Brown has a flattering scoop neckline, a low scoop back and a high-cut leg, in a soft, high-stretch textured fabric.
Ruching
Ruching is fabric gathered into soft folds. On the bust, it adds texture and volume and draws the eye. The Alba Ruched U-Wire Swimsuit in Chocolate Brown combines a softly ruched bust with a sculpted U-wire neckline, wide shoulder straps and a high-cut leg. It is also available as the Alba Ruched U-Wire Swimsuit in White.
U-wire and underwired tops
A U-wire or underwired top gives the bust structure and shape, much like an underwired bra. It suits anyone who likes to feel held and defined. The Shae Swimsuit in Brown has underwired cups, a V neckline and a second-skin fit that give it subtle structure. For a bikini, the Monaco Muse Two-Tone Underwire Bikini Set in Black has a balconette-style underwire top with a secure front clasp that lifts and shapes, with high-cut bottoms that lengthen the legs.
Plunge necklines
A plunge neckline lengthens the torso and frames the décolletage. It is a confident, glamorous choice for any bust size. The Black Plunge One-Piece Swimsuit with Gold Accent has a deep plunge front held by a gold-tone lion-head detail, a tie halterneck and a flattering high-cut leg.
Halter necks
A halter neck ties or fastens behind the neck, drawing the eye upward to the shoulders and collarbones. It is a fresh, summery shape, especially in bikinis. The Lucy Halter Bikini Set in Chocolate Brown has a halter triangle top with soft gathered cups, removable padding and a gold-tone charm at the centre front.
Removable padding
Removable padding gives you choice. Wear the padding for extra shape and coverage, or remove it for a more natural feel. Many of our swimsuits and bikinis, including Alba, Sienna and Lucy, have removable padding, so you can adjust them to suit you.
Best swimsuits for a small bust
If you have a small bust, you can wear almost anything, and many styles are especially flattering. Ruching adds texture and the look of volume, so the Alba ruched swimsuit is a wonderful choice. Removable padding gives you the option of a little extra shape. Halter necks and triangle bikinis, such as Lucy, suit a smaller bust beautifully, while a plunge neckline is chic and confident.
For bikinis with a small bust, look for gathered or ruched cups and adjustable straps. The Liberty Black Bikini with Gold Buckle has ruched cups that meet at a gold-tone centre buckle, with adjustable straps for a customised fit.
Best swimsuits for a fuller bust
If you have a fuller bust, structure and coverage are your friends. U-wire and underwired tops lift and shape, so the Alba or Shae swimsuit is a natural choice. Wide shoulder straps, like those on Alba, feel secure. Balconette-style underwire bikinis, such as Monaco Muse, offer shape and a front clasp that is easy to fasten. A scoop neckline, like Sienna's, gives lovely coverage with a clean, minimal look.
Pear, hourglass, rectangle and apple shapes
If you find body-shape guides useful, here are some gentle ideas.
- Pear: if your hips are wider than your shoulders, a detailed top, such as a halter or a ruched bust, draws the eye upward. High-cut legs lengthen the legs.
- Hourglass: if your bust and hips are balanced with a defined waist, almost anything works. A plunge or a U-wire celebrates your curves.
- Rectangle: if your bust, waist and hips are similar, ruching and high-cut legs add shape and movement.
- Apple: if you carry more around your middle, a plunge neckline lengthens the torso, and underwired tops give structure.
These are suggestions, not rules. Wear what you love. Our guide to choosing lingerie for your body type explores more ideas.
Swimsuit or bikini?
A swimsuit gives a sleek, streamlined look and doubles as a bodysuit for evenings, worn with a skirt or wide-leg trousers. A bikini shows more skin, lets you mix sizes or styles of top and bottom, and is perfect for sunbathing. Many people pack both for a holiday. Browse our swimsuits, our bikinis or all our swimwear.
Colour and print
Colour changes how a swimsuit looks and feels. Black is classic and sleek. White is fresh and luminous, especially against a tan. Chocolate brown is warm, rich and flattering on a wide range of skin tones, and our Chocolate Brown edit brings together swimwear, lingerie and loungewear in the same beautiful shade. Gold-tone details, like those on Lucy, Liberty and the Black Plunge swimsuit, add a touch of glamour to any colour.
Fit tips for buying swimwear online
Choose your usual UK size and read the fit notes on each product page. Swimwear should fit closely. Try it on at home, then sit, stand and move about to check that the straps stay put and the fit feels secure. If you are between sizes, consider your bust and your hips, and choose for the area where you want more room.
Swimwear for holidays: what to pack
For a week away, two or three swimsuits and bikinis are usually plenty. Pack one sleek one-piece that doubles as a bodysuit for evenings, one bikini for sunbathing and one in a different colour or style for variety. Chocolate brown, black and white all mix easily with neutral cover-ups and gold jewellery, which keeps your case light.
Caring for your swimwear
Rinse your swimwear in cool, fresh water after every swim, and lay it flat to dry in the shade. Avoid wringing it out or leaving it in a wet bag, and always follow the care label on each piece. A little care helps your swimwear keep its shape and colour season after season.
Confidence is the best accessory
Whatever your shape, the swimsuit that suits you best is the one you forget you are wearing. Choose a fit that feels secure, a colour that makes you smile and details that celebrate the parts of you that you love. Then pack your sunglasses and enjoy the sun.
Trying on at home
When your swimwear arrives, try it on with the bikini or swimsuit bottoms over your underwear, in good light and in front of a full-length mirror. Raise your arms, bend and twist, so you know how it feels when you are swimming or lounging by the pool.
Building a swimwear wardrobe over time
You do not need a suitcase full of swimwear. Start with one versatile one-piece in a colour you love, such as black or chocolate brown, then add a bikini for sunbathing. Over time, add a statement piece, such as a plunge halterneck or a white swimsuit for a honeymoon or special trip. Choose pieces with details you love, like ruching, a high-cut leg or gold-tone hardware, and they will feel special every time you wear them. Mixing a few well-chosen styles gives you options for every beach, pool and holiday, from a lazy week by the sea to a city break with a rooftop pool.
