There is a particular moment every summer when the swimsuit drawer gets its annual audit. Last year's pieces come out, a few get a second chance, and one question comes up again: what, exactly, makes a one piece swimsuit worth keeping? At Tuchuzy, we have been fitting swimwear from Hall Street in Bondi Beach since 1995, and the answer has stayed refreshingly consistent. The best one piece is the one you stop thinking about the moment you put it on.
This is our plain-spoken guide to choosing one: how to think about neckline and coverage, which shapes suit which kind of day, how to build a beach bag around it, and how to look after it so it lasts more than a single season. Wherever you are reading from, Tuchuzy ships worldwide, including to the United States, so the northern summer and the southern one are equally welcome here.
Why the One Piece Is Having a Long Moment
A one piece swimsuit does something a bikini cannot: it doubles as a bodysuit. Throw a pair of linen shorts or a wrap skirt over it and you are dressed for lunch without a single change of clothes. That is why so many of our Bondi regulars own one for the water and one for the walk home, with the same suit working from the first swim of the morning to the last drink on the terrace.
It also happens to be the most forgiving shape for long, active beach days. Swimming laps at Bronte Baths, a paddle at Tamarama, an afternoon of chasing a small person along the sand at Clovelly: a one piece stays where you put it. If you want the full range, the designer swimwear collection brings every label together in one place, and it is the best starting point for comparing shapes side by side.
Start With the Neckline
Necklines decide almost everything about how a one piece feels, so begin there rather than with colour.
A square neck is the clean, architectural choice. It frames the collarbones, sits well under a shirt worn open over the top, and looks as good at a hotel pool as it does on a headland walk. The Hunza G Square Neck Swim in black is a good example of the shape, and it is in healthy stock right now. If black is not your colour, the same silhouette lives in the wider Hunza G collection, so you can follow the shape into other shades as stock moves.
A halter or high neck lifts the line of the shoulders and gives you a little more support, which makes it a sensible pick for swimming rather than lounging. A scooped or plunging neckline is the opposite: softer, more sun-seeking, and a natural partner for a pair of statement earrings from the jewellery edit once you are dry.
Then there is the strap. Wide straps feel secure and sporty. Thin straps feel delicate and dressy. Cross-back and tie styles let you adjust the fit across the day, which is handy when the water is cold and the swim turns into a long lie in the sun.
Cut, Coverage and the Honest Question of Comfort
The leg line matters as much as the neckline. A high-cut leg lengthens and is flattering, but it is not for everyone. A moderate cut gives you more coverage through the hip and is generally easier to wear for a full day. Back coverage is its own conversation: a low back is lovely for tanning and awkward for tennis, so choose according to what you will really be doing.
Our rule of thumb is simple. If you plan to swim properly, choose more coverage and more structure. If the plan is a long lunch beside the water, choose the shape that makes you feel most like yourself. The point of swimwear, after all, is to spend less time adjusting it.
Fit is the part you cannot fake. A good suit should feel snug without digging, with straps that stay put and a body length that does not pull at the shoulders. If you are between sizes or shopping a label for the first time, the visit us page has everything you need to find us on Hall Street, and our team is always happy to talk through fit by message too.
A Few Shapes Worth Knowing
The Hunza G Domino Swimsuit in blush is the softer end of the story: a gentle colour that reads as neutral against tanned skin, and a shape that moves easily from pool to poolside lunch. Like most Hunza G pieces, it is built around the label's signature crinkled, stretchy fabric, which is part of why the brand has such a loyal following. Because individual colours sell through quickly, the safest way to browse is the Hunza G collection, where the current range is always up to date.
If your taste runs toward something more sculpted, the Fae Swim collection is worth a look. Fae is a label we stock for its clean, considered cuts and it sits comfortably next to Hunza G in a suitcase. For a more graphic, contemporary take, Montce Swim is the third name we would point you to. Three labels, three different moods, one very easy edit.
Building the Beach Bag Around It
A one piece swimsuit is the easiest swim piece to pack around, because everything else is optional. We tend to think in layers.
Start with something to throw over the top. A beach robe is the most practical for the walk to and from the water, while a pair of tailored shorts or a wrap skirt turns the swimsuit into an outfit. Add designer sunglasses for glare off the water, a hat from the hats collection for the long middle of the day, and a beach bag big enough to hold a towel, a book and a wet suit on the way home. A generous beach towel in a neutral tone will go with everything.
That is the whole kit. It is deliberately simple, because the best beach days are the ones where you are not carrying much.
Colour: Black, Neutral or Something Brave
Black is the classic for a reason. It is slimming, versatile and forgiving of sunscreen and sand. A neutral such as blush, cocoa or white feels warmer and photographs beautifully. A bolder colour gives a plain wardrobe a lift and is easy to wear once you commit to it.
If you are buying one suit to last, black or a deep neutral is the investment colour. If you already own the basics, let yourself be braver with the second. There is no wrong answer, only the one you will actually put on.
Looking After It
Swimwear lives a hard life: salt, chlorine, sun and sunscreen all take their toll. A few small habits make a real difference. Rinse your suit in fresh water as soon as you can after swimming, and do not leave it wet in a bag for the afternoon. Wash it by hand in cool water with a gentle soap, then lay it flat in the shade to dry rather than wringing or tumbling it. Direct sun and hot water are the enemies of colour and stretch.
Rotating two suits also helps, because fabric needs a day to recover its shape. It is the same logic as owning two pairs of everyday shoes, and it is why many of our customers buy their one pieces in pairs.
Your Questions Answered
How do I choose the right one piece swimsuit for my body? Begin with what you want to feel: supported, free, or somewhere in between. Pick a neckline you like, check the leg line and back coverage against your plans for the day, and focus on fit through the torso. A suit that feels right in the fitting room will feel right in the water.
Is a one piece better than a bikini for swimming? Generally, yes, because it stays put through waves and laps. That said, many bikinis are designed with swimming in mind, so choose the fit rather than the category.
How do I make a one piece swimsuit last? Rinse after use, hand wash in cool water, dry flat and out of direct sun, and rotate between two suits where you can.
What should I wear over a one piece swimsuit? Anything easy: linen shorts, a wrap skirt, an open shirt, or a towelling robe. The linen edit is especially good for this.
Do you ship swimwear internationally? Yes. Tuchuzy ships worldwide, including across Australia and to the United States, so you can shop the edit from wherever the sun is.
