The best luxury swimsuit brands design beautiful clothing that happens to be waterproof. A swimming suit is equipment. The difference is not snobbery: designer swimwear is typically cut from nylon-elastane blends that go baggy and translucent after a few months of chlorine, with thin straps and low backs that shift the moment you push off a wall. If you swim lengths, own a polyester or PBT training suit. If you sit by a pool, buy whatever you love. Owning both is entirely reasonable and considerably cheaper than expecting one suit to do both jobs.
I have no argument with beautiful swimwear. I have an argument with people who buy it, swim in it three times a week, and then conclude that all swimsuits fall apart.
What Chlorine Does

Elastane — the stretchy fibre that gives most fashion swimwear its shape — degrades in chlorinated water. The suit loses recovery, sags at the seat, and eventually goes sheer when wet. Sunlight and heat accelerate it. A humid Singapore pool bag left closed overnight accelerates it further.
Polyester and PBT do not do this. A polyester training suit will hold its shape for a year or more of regular swimming, and it is why every swimmer in a squad lane is wearing one, in unglamorous navy.
The trade-off is honest: training suits are cut for function, they are less flattering, and nobody has ever described one as elegant.
Clothing or Equipment?
| Designer / luxury swimwear | Training suit | Racing suit | |
|---|---|---|---|
| Fabric | Usually nylon-elastane | Polyester or PBT | Technical woven fabric |
| Chlorine life | Weeks to months | A year or more | Very limited; race use only |
| Support | Variable, often minimal | Genuine, with a proper back | Compressive |
| Comfort on a push-off | Rides, shifts, gapes | Stays exactly where it is | Tight by design |
| Cost per swim | High | Low | Very high |
| Best used for | Beach, holiday, poolside | Lessons, lengths, squad | Competition |
What to Look For in a Suit You Will Swim In

- Fabric first. Read the label. Polyester or PBT for training. Anything with a high elastane content is a fashion suit.
- The overhead test. In the changing room, reach both arms straight up. If the suit pulls down at the shoulders or gapes at the chest, it is too short in the body.
- Straps. Racerback or crossback. Wide. Thin straps and heavy busts are a shoulder problem waiting six weeks to happen.
- Leg line. Higher legs mean fewer adjustments mid-length. A modest leg cut in a training suit is fine.
- Lining. A fully lined front, always. Check by holding it up to light.
- Fit. Snug when dry. Every suit loosens in water.
For men, jammers or briefs rather than board shorts. Board shorts create enormous drag, they will not stay up on a wall push-off, and many pools do not permit them.
Making Any Suit Last Longer
- Rinse in cold fresh water immediately after every swim.
- Never wring it out. Press the water out instead.
- Dry flat, in shade, never in a car or a hot bathroom.
- Never leave it balled up in a wet bag overnight.
- Rotate two suits if you swim more than twice a week.
- Keep it away from hot tubs, which are chemically hostile.
Common Mistakes
- Buying a designer suit for lap swimming. Beautiful, expensive, briefly opaque.
- Racing suits for training. They are consumable, uncomfortable, and wasted on a Tuesday session.
- Board shorts in a lane. Drag, and often not permitted.
- Ignoring the overhead test. The single most useful thirty seconds in the changing room.
- Wringing the suit out. It destroys the fibres faster than the chlorine does.
- Buying on the belief a suit will make you faster. For an ordinary swimmer, technique does that, and nothing else comes close.
A Note on Comfort and Confidence
A great many adults do not learn to swim because they do not want to be seen in a swimsuit. That is a real barrier and it deserves a practical answer rather than a lecture.
Wear a rash guard or a long-sleeved swim top. Wear swim leggings. Wear a modest suit designed for full coverage — they exist, they are made in proper fabrics, and nobody in a lane will look twice. Book a quiet lesson time. Adults in one-to-one private lessons often choose an early morning or a mid-afternoon pool precisely for this reason, and any decent coach will accommodate it without comment.
You can read about modest swimwear you can actually swim in, and about maternity swimwear built for lengths. For learners wanting company rather than solitude, small-group swimming classes work well, and swimming near me will find a quieter pool.
Safety, Briefly
A swimsuit is not safety equipment and neither is anything worn over it. No garment keeps a non-swimmer afloat. Children need an adult within arm’s reach regardless of what they are wearing, and inflatable toys are not flotation devices.
Swim where there is a lifeguard, and never let anyone hold their breath underwater as a game — breath-holding can cause shallow-water blackout, a silent loss of consciousness that has drowned strong swimmers.
In an outdoor pool, a long-sleeved swim top does more for sun protection than repeated sunscreen, and reapplication after every swim is still necessary on exposed skin.
Frequently Asked Questions
Are luxury swimsuit brands worth the money?
For the beach and the poolside, they sell design and finish, and that is a legitimate thing to buy. For swimming lengths, they are the wrong tool at a high price.
What fabric should a swimming suit be?
Polyester or PBT. Both resist chlorine well. Nylon-elastane blends, common in fashion swimwear, break down quickly.
How long should a training suit last?
With rinsing and shade drying, a year or more of regular swimming. Rotating two suits roughly doubles that.
Can I swim laps in a bikini?
You can, and plenty do, but there is little support and it moves on every push-off. A one-piece or a training two-piece with a proper back is far less distracting.
Should men wear jammers or briefs?
Either. Both create far less drag than board shorts, and both stay put. Choose on comfort.
Does an expensive suit make me faster?
Racing suits offer marginal compression benefits to competitive swimmers at race pace. For everyone else, the gains sit entirely in technique.
