The best swimsuit for lap swimming should fit securely, let you move freely, and hold up through your routine. But finding the right one isn’t always easy. A suit may fit your hips but pull at your shoulders, feel comfortable when dry but shift in the water, or lose its shape after repeated pool workouts.
At See Her Swim, we believe choosing the right swimsuit starts with understanding your body’s proportions, the suit’s construction, and how often you swim.
One-Piece or Two-Piece: Which Is Better for Lap Swimming?
A one-piece swimsuit offers continuous coverage and can be a great choice for regular lap swimming. However, women with longer torsos may find that some styles pull uncomfortably at the shoulders or crotch.
A two-piece swimsuit offers more flexibility if you have a fuller bust and narrower hips because you can choose different sizes for the top and bottom. As long as both pieces fit securely during movement, it can also work well for swimming laps.
How Should a Swimsuit Fit for Lap Swimming?
Your swimsuit should feel snug without digging into your skin, restricting movement, or pulling uncomfortably across your torso. It should stay in place when you reach, kick, and turn.
Pay attention to three areas:
- Straps and bust support: Adjustable straps can help you fine-tune the fit. Strap width and construction also affect how a swimsuit feels, so don’t assume every style in the same size will fit the same way. Thick straps have more elastic, like the Backstroke- .https://shop.seeherswim.com/collections/discover-the-collection-see-her-swim/products/the-backstroke-one-piece?variant=40799366185123 Thin straps may have less elastic, like the Breaststroke- https://shop.seeherswim.com/collections/discover-the-collection-see-her-swim/products/the-breaststroke-one-piece?variant=40799095095459
- Leg openings and coverage: A high-cut leg or more minimal back may feel different from a full-coverage design. Choose a cut that stays comfortable and secure during movement.
- Torso length: If your suit constantly pulls at your shoulders, the torso may be too short. Sizing up might help, but it can also leave excess fabric elsewhere.
If you’re wondering, “Why does my swimsuit ride up when I swim?” check the size, torso length, leg opening, and overall cut. When trying on a suit, reach overhead, rotate your shoulders, and bend as you would during a workout. Persistent pulling or shifting may mean another size or style is a better fit.
What Swimsuit Fabric Is Best for Chlorinated Pools?
If you swim frequently, fabric durability matters. Chlorine, sunlight, repeated stretching, and regular wear can gradually affect a swimsuit’s color, elasticity, and shape.
Polyester and some PBT blends are popular in training swimwear because they resist chlorine-related degradation. Lycra and spandex provide softness and stretch, but elastane-containing fabrics can lose elasticity over time with repeated exposure to chlorine, heat, and sunlight.
A lining can also provide additional coverage and structure, helping reduce sheerness when the fabric is stretched. However, opacity depends on the overall fabric, color, construction, and fit—not just whether the suit is lined.
Your Lap Swimming Swimsuit Checklist
Before buying your next women’s performance swimsuit, ask yourself:
- Does it fit comfortably through my torso, bust, and hips?
- Can I move freely without the straps digging in or the fabric shifting?
- Is the fabric suited to how often I swim?
- Does the suit provide the coverage and support I prefer?
- Have I checked the brand’s size guide?
