Pregnancy Swim Suits: Fit, Support and Swimming Comfortably

Pregnancy Swim Suits: Fit, Support and Swimming Comfortably

A good pregnancy swim suit has three things: a panel or cut that expands over the bump without riding up, real bust support with adjustable straps and a wide underband, and chlorine-resistant fabric that keeps its shape as your body changes. Most women need one suit bought around the second trimester rather than several bought early. Before swimming during pregnancy, speak to your doctor or midwife — for most uncomplicated pregnancies they will encourage it, but that is their call, not an article’s.

Swimming is the exercise pregnant women are most often recommended, because the water carries the weight the body is suddenly asked to carry. Buoyancy takes the load off the pelvis, hips and lower back. Many women who have stopped running or lifting keep swimming right through, and are glad of it.

Then they try to swim in a pre-pregnancy swimsuit and give up after two lengths. The suit, not the swimming, was the problem.

What changes, and what the suit must accommodate

• The bump grows unevenly and unpredictably. A suit that fits at twenty weeks may not at thirty.
• The bust changes early and often significantly. Support becomes more important than it was.
• The rib cage widens. Underbands that fitted before will dig in.
• Shoulders take more strain. Thin straps cut in when the bust is heavier.
• Fabric stretches faster. A suit stretched over a growing bump loses recovery quickly, and chlorine accelerates this.

Buying well

1. Wait until the second trimester for the main purchase. Early on, your existing suit or a size up usually suffices.
2. Check the front rise. The panel should reach up over the bump, not stop underneath it. Lift your arms overhead in the fitting room; if it rides up, it will ride up in the pool.
3. Buy for the bust you have now. Wide adjustable straps, a supportive underband, no thin spaghetti ties.
4. Choose chlorine-resistant fabric — polyester or a polyester-PBT blend — if you swim regularly. Standard elastane degrades within weeks of frequent pool use, and a stretched suit gapes.
5. Test the leg openings seated. They should not cut in.
6. One good suit beats three cheap ones. You will wear it constantly for a few months.

Common mistakes

• Sizing up an ordinary suit. It gets longer everywhere except where you need it, and gapes at the back.
• Buying at eight weeks for a body you will have at thirty. Guessing wastes money.
• Ignoring bust support because the focus is on the bump.
• Cheap elastane in a chlorinated pool. Baggy within a month.
• Not rinsing after every swim. A freshwater rinse roughly doubles a suit’s life.
• Assuming you must stop swimming. For most uncomplicated pregnancies, the opposite advice applies — but ask your doctor.

Safety in the pool while pregnant

The single most important line in this article: talk to your doctor or midwife before you start or continue any exercise in pregnancy, and follow their advice over anything written here. Individual circumstances differ enormously, and only they know yours.

Beyond that, some general practicalities. Pool decks are slippery and your balance and centre of gravity have shifted — walk, hold the rail, use the steps rather than the ladder. Avoid diving and jumping in. Avoid hot tubs, spas and very warm pools; raised core temperature in pregnancy is a recognised concern. Do not swim alone. Get out if you feel dizzy, breathless beyond normal exertion, or unwell, and stop immediately and seek medical advice if you experience bleeding, contractions, fluid loss, or pain.

Never hold your breath underwater for distance or duration. Extended breath-holding can cause shallow-water blackout, a loss of consciousness without warning that has killed strong swimmers. There is no version of this that is appropriate during pregnancy.

Breaststroke sometimes aggravates pelvic girdle pain because of the wide kick. If it hurts, switch to freestyle or backstroke, or use a gentler flutter kick, and mention it to your physiotherapist or midwife. Pain is a signal to change something, not to persist.

Swimming through pregnancy

Many women find aqua fitness and deep water exercise more comfortable than lap swimming late in pregnancy, because being suspended takes all the load off the pelvis. Others swim gentle lengths until the week they give birth. Both are reasonable if your doctor is content.

Warm up gently — our warm-up guide applies, with less intensity. If you are not a confident swimmer and want to be in the water safely, private swimming lessons in your own condo pool avoid crowded public sessions entirely, and a swimming coach can adjust strokes around what your body will tolerate.

Frequently asked questions

When should I buy a maternity swimsuit?

Usually in the second trimester, when the bump has established itself. Before that, your existing suit or a size up generally works.

Is swimming safe during pregnancy?

For most uncomplicated pregnancies it is widely recommended, but ask your doctor or midwife. They know your circumstances; an article does not.

Can I swim in an ordinary swimsuit while pregnant?

Early on, yes. As the bump grows, an ordinary suit rides up at the front and gapes at the back, which is uncomfortable and makes swimming harder.

Which stroke is most comfortable in pregnancy?

It varies. Many women prefer backstroke in the second trimester and find breaststroke aggravates pelvic pain. Choose by comfort, and mention pain to your midwife or physiotherapist.

Are hot tubs and warm pools safe?

Hot tubs and spas are generally advised against in pregnancy because of raised core temperature. Ask your doctor about specific pool temperatures.

How do I make my swimsuit last?

Buy chlorine-resistant fabric, rinse in fresh water after every swim, dry in shade, and do not wring it out hard.

Get the suit right, ask your doctor, and enjoy the one place where you are not carrying the weight.
