1Getting a wet suit off takes longer than it used to.

This is the single most common complaint, and the one no brand will print. Wet fabric grips. Arms go over the head. A shoulder that was fine yesterday is suddenly the deciding factor in whether you swim at all. Four-way stretch is not a luxury feature here — it is the difference between a suit you wear and a suit you avoid.

2Your shoulders will tell you about that halter neck tomorrow.

A halter hangs the whole weight of the suit from two narrow points on the back of your neck. For twenty minutes it is nothing. For an afternoon it is a headache. Wider straps and a back that spreads the load are not a style choice; they are why you can stay in the water longer.

3Chlorine is harder on swimwear than the sun is.

Everyone blames sunlight. In practice it is chlorine and, more than that, heat — a suit rolled wet into a bag in a hot car ages faster than one hung in the shade. Rinse in cool water, dry flat out of direct sun, never wring. That advice costs us money and it is still the right advice.

4Sunscreen on your own back is a two-person job.

Nobody plans for this and everybody deals with it. The practical answer is not more sunscreen, it is fabric: a suit rated UPF 50+ across every panel covers the part of your back you cannot reach without help. That is one less thing to organise before you get in the water.

Worth saying plainly what this is and isn’t. UPF rates how much ultraviolet the fabric blocks. It does nothing for the skin the suit doesn’t cover, and it is not a substitute for shade, a hat, or sunscreen everywhere else.

5Sizing anxiety is worse than sizing.

Bodies change, and most of the dread around buying swimwear is really dread about the number on the label. There is a quiet argument for a range that groups sizes rather than pinning you to one: you pick the band you are in and stop thinking about it. The suit still has to fit. You just stop being asked to declare a number first.

6A suit that dries on you is warmer than a towel.

The cold does not come from the water. It comes from twenty minutes afterwards in a heavy wet suit while everyone else packs up. A fabric that sheds water quickly keeps you comfortable long after you are out — which in practice is what decides whether you get in a second time.

7Buy for the water you will actually be in.

Be honest about it. If it is a hotel pool twice a year, almost anything will do and you should not spend much. If it is laps, or the ocean, or three months of Australian summer, buy the better fabric once and stop replacing the cheap one. Most women we hear from made the second mistake repeatedly, and it cost more than the first purchase would have.
