Every summer starts the same way in Bondi. The first truly warm Saturday arrives, the beach fills by nine, and half the women we know realise at roughly the same moment that last year's swimwear is tired, stretched or missing a piece. The bikini set is the swim purchase most of us make most often, and it is the one most worth getting right, because a good one gets worn from the first ocean swim of spring to the last long weekend of autumn.
This is our guide to choosing bikini sets that actually work: how to think about tops and bottoms as a pair, how to mix them without it looking accidental, and which labels on our floor do it best this season. It is written from the shop on Hall Street, a few minutes from the sand, where we have been helping women choose swimwear since 1995.
Think in Pairs, Then Think in Pieces
The simplest bikini set is a top and bottom in the same fabric and colour, bought together. It is the easiest place to start because the proportions have already been considered for you: the coverage of the top and the cut of the bottom are designed to balance each other. If you are buying one set this summer, buy a matching one in a colour you will never tire of.
The smarter long-term approach, though, is to treat each half as its own decision. Your top size and bottom size are often different, the support you need on top has little to do with the coverage you want below, and the best swim wardrobes are built from pieces that can be recombined. Several of the labels we carry in depth, Janthee and Fae Swim among them, sell tops and bottoms separately, which means you can choose an underwired top for support and a cheekier bottom for the tan, or the reverse, without compromising on either.
The full luxury swimwear edit is the place to see every cut side by side. Below is how we would narrow it down.
Janthee: The Set That Adjusts to You
If there is one label on our floor that has made the bikini set feel new again, it is Janthee. The pieces are ethically sewn in Portugal from Italian fabrics, including a silky Xtra Life Lycra that holds its shape, and many of them are designed to adjust, so one set can look several different ways across a holiday.
For support, the Janthee Emilia Top in Fuchsia is a sculpted underwired top with delicate ruching across the cups, adjustable straps and a gold clasp. Pair it with the matching Janthee Alexia Bottom in Fuchsia, a Brazilian bottom with ruching across the back and flatter side straps that sit comfortably without digging in, and you have the most complete set we sell this season. The same pairing comes in other colourways, so check the Janthee edit for the full range.
If you want a top that does more than one job, the Janthee Mary Top in Moss has long adjustable straps that can be styled in a number of different ways. Match it with the Janthee Luna Bottom in Moss, whose ultra-thin straps tie at the sides or wrap around the waist, and the set changes shape as often as you do. For a classic triangle, the Janthee Dalia Top in Asako ties at the neck and back so you can set the support yourself, and it sits beautifully with the tie-side Janthee Amal Bottom if you want a deliberate contrast between a soft neutral on top and a vivid colour below.
Hunza G: One Fabric, Endless Repeat Wear
Hunza G is the label our customers buy once and then keep buying. Its signature Original Crinkle fabric has a textured hand and a natural stretch that flexes and sculpts, which is why the label works on a one-size principle that suits a body changing across a week of holiday. The Hunza G bikinis on our floor are sold as sets, so the top and bottom arrive together in the same crinkle and colour.
The Hunza G Xandra Bikini in Black is the square-neck two piece, clean and understated, the set to choose if you want swim that reads as considered under an open shirt on the walk to lunch. The Hunza G Jean Bikini in Black and the Hunza G Gigi Underband Bikini in Black give you two more shapes in the same dependable colour. Seasonal shades rotate quickly, so the current line-up is best seen in the Hunza G bikini edit, and the wider Hunza G collection holds the one pieces and resort pieces that sit alongside them.
Mix and Match Without It Looking Accidental
Mixing a top and bottom from different sets is the fastest way to stretch a swim wardrobe, but there is a difference between a deliberate pairing and one that looks like the other half went missing. Three rules keep it intentional.
First, keep one element constant. Either the colour matches and the cut changes, or the cut family matches and the colour changes. A fuchsia underwired top with a fuchsia tie-side bottom works because the colour holds it together. A soft neutral triangle with a moss Brazilian bottom works because both pieces sit in the same earthy register.
Second, match the hardware. Gold clasps with gold rings, or no hardware at all. Mixed metals on a bikini read as an accident rather than a choice.
Third, match the fabric family. A crinkle top with a smooth Lycra bottom can look off, because the textures catch the light differently. Stay within one label, or at least one fabric type, when you mix. For more on building a swim wardrobe from separates, our mix-and-match bikini guide goes deeper on the Fae Swim approach, and our Brazilian-cut bikini edit covers the cheekier end of the spectrum through Montce Swim.
Choosing the Right Set for Your Summer
The right bikini set depends less on body type than on how you actually spend your days by the water. Ask yourself what you do in it.
If you swim properly, laps at an ocean pool or a long swim between the flags, choose an underwired or square-neck top that stays put and a bottom with a little more coverage. If your summer is mostly lying on a towel, reading and turning over every half hour, a triangle top and a cheekier bottom will give you a more even tan. If you travel, choose pieces that adjust, so one set can become three looks and the suitcase stays light. And if you are building your first set from scratch, start with black, then add colour once you know which cuts you reach for most.
It is also worth thinking about what goes over the top. A bikini set that looks right with a linen shirt or a towelling robe will get worn far more than one that only works on the sand. The beach robe and swim accessories edits are where we finish the look, and a pair from the designer sunglasses edit completes it.
If you prefer a single piece for some days, our guide to choosing a one piece swimsuit is the companion to this one, and between the two you can build a swim wardrobe that covers every kind of beach day.
Fit and Care
Swimwear sizing is personal, so try a set on with the light behind you and move in it: sit, stretch, lift your arms. The top should not shift when you raise them and the bottom should sit flat at the sides without cutting in. Rinse every piece in cool fresh water after salt or chlorine, wash gently by hand and dry flat in the shade, because direct sun fades colour and tires elastic faster than anything else.
If you are close by, the easiest way to solve all of this is in person. Come and visit us on Hall Street and we will help you pair a top and bottom properly. If you are further away, Tuchuzy ships worldwide, including across Australia and to the United States, so your bikini set can arrive before your next summer does, wherever that is.
Your Questions Answered
Should I buy a matching bikini set or mix tops and bottoms?
If you are buying one set, buy a matching one in a colour you love. Once you have a base, mixing tops and bottoms from the same label or fabric family is the best way to stretch your swim wardrobe without buying more.
Can I wear a different size top and bottom?
Yes, and many women do. Labels such as Janthee sell tops and bottoms separately, so you can choose the support you need on top and the fit you want below independently.
What is the most flattering bikini set?
The one that matches how you spend your day. An underwired or square-neck top with a mid-coverage bottom flatters and supports for swimming, while a triangle top with a Brazilian bottom suits lounging and a more even tan.
How do I make a bikini set last more than one summer?
Rinse it in cool fresh water after every swim, hand wash gently, dry flat in the shade, and rotate between two sets so each one has time to recover between wears.
Do you ship swimwear to the United States?
Yes. Tuchuzy ships worldwide from Bondi, including to the United States, so you can shop our full swim edit wherever you are.
