One-Piece vs Two-Piece Swimwear for Swimming Lessons

When parents are buying girls swimwear for weekly swimming lessons, one question comes up all the time: should you choose a one-piece or a two-piece swimsuit?

At the beach, both can work perfectly well. But swim lessons are different. There is diving, floating, kicking drills, climbing out at the wall and jumping back in again — often over and over for 30 to 45 minutes straight.

THE BEST SWIMWEAR FOR SWIM LESSONS IS THE ONE THEY DON’T HAVE TO THINK ABOUT.

That is why many Australian parents eventually move towards secure one-piece training swimwear for regular lessons, school swimming and squad sessions.

IS A ONE-PIECE OR TWO-PIECE BETTER FOR SWIMMING LESSONS?

For regular swimming lessons, most parents find that one-piece swimwear is easier because it stays secure in the water and needs less adjusting during class.

During lessons, children are constantly moving. Between kicking practice, floating drills and climbing out of the pool, swimwear that shifts around can quickly become distracting — especially for younger swimmers still building water confidence.

That does not mean two-piece swimwear is bad. For beach holidays, backyard pool days and relaxed weekend swimming, many girls love wearing two-pieces.

But once swimming becomes part of the weekly school routine, parents often start prioritising practicality, support and secure coverage instead.

WHY ONE-PIECE TRAINING SWIMWEAR WORKS WELL FOR KIDS

One-piece training swimwear is designed to stay comfortably in place during active swimming lessons, helping kids focus on swimming instead of adjusting their swimsuit.

Many girls training swimsuits use racerback or cross-back designs because they help straps stay secure while still allowing full shoulder movement through freestyle and backstroke drills.

For regular swim lessons, small details make a big difference over time. Thick shoulder straps feel more supportive, soft lining improves comfort, and chlorine resistant fabric helps swimsuits keep their shape week after week.

WHEN TWO-PIECE SWIMWEAR STILL MAKES SENSE

Two-piece swimwear can still be a great option for beach swimming, holidays and relaxed recreational pool time.

Some children simply prefer the feel or style of a two-piece swimsuit, and for casual swimming there is absolutely nothing wrong with that.

But for structured swim lessons — especially lessons involving diving, jumping or longer training sessions — some two-piece styles can move around more easily in the water. Over time, that constant adjusting can become frustrating for children trying to focus on learning.

WHAT TO LOOK FOR IN GIRLS TRAINING SWIMWEAR

The best girls training swimwear is secure, chlorine resistant and comfortable enough for regular weekly pool use.

When shopping for swimming lessons, look for swimwear made specifically for training rather than occasional holiday swimming.

• Chlorine resistant fabric, not everyday fashion swim fabric that loses shape quickly
• Thick supportive shoulder straps that stay secure during lessons
• Secure racerback or cross-back designs for unrestricted movement
• Soft lining for comfort during longer sessions
• UPF50+ sun protection for outdoor swimming and school carnivals

At Lesimo, our girls training swimwear is made with DuraFlex Performance Fabric to help swimsuits stay supportive, comfortable and secure through regular swim lessons and squad training.

LESS ADJUSTING, MORE CONFIDENCE IN THE WATER

For weekly swim lessons, many parents find that secure one-piece swimwear helps children feel more comfortable and confident in the water.

Both one-piece and two-piece swimwear have their place. But when swimming becomes part of the weekly routine — especially during busy school terms and early morning lessons — practical swimwear simply makes life easier.

Less adjusting. More swimming. More confidence every lesson.
