Learn how to pick the right size and care for your Core Bikini Bottom so it keeps its shape and color. Simple steps for fit, washing, and storage.
Quick answer
Choose your usual size for a mid-rise fit that follows your natural curve, then hand-wash in cool water after each wear and dry flat in the shade. This keeps the double fabric and invisible seams in good shape.
Why the double fabric changes your care routine
The Core Bikini Bottom is made from double fabric throughout, which gives it a substantial feel and helps it hold its shape. That extra layer also means it holds more water and takes longer to dry than a single-layer bottom. Rinse it thoroughly after every swim to remove salt, chlorine, and sunscreen, and never wring it out—twisting can stretch the seams. Instead, press it gently between your palms or roll it in a towel.
When to size up or down
The mid-rise cut and invisible seams are designed to sit comfortably on your natural curve, so most people should start with their usual size. If you prefer more coverage in the back, the Core Bikini Bottom already offers a moderate amount; sizing up will add a little more room but may change how the waistband sits. If you are between sizes, consider how you like your swimwear to feel: a snug fit stays put in the water, while a looser fit feels lighter but may shift during activity.
Step-by-step: fit and care for your Core Bikini Bottom
- Check the size chart before ordering: Measure your hips and waist, then compare with the size chart. The Core Bikini Bottom is designed to follow your natural curve, so your usual size is the best starting point. Common mistake: guessing based on other brands—swimwear sizing varies, so always use the chart. If your measurements fall between two sizes, choose the larger size for more coverage.
- Try it on with the tags on: Wear the bottom briefly over your underwear to check the waistband and back coverage. It should feel snug but not tight, and the seams should lie flat. Common mistake: removing tags before checking fit—you cannot return swimwear without hygiene protection. Squat and stretch to make sure the bottom stays in place.
- Rinse immediately after every swim: As soon as you leave the water, rinse the bottom in cool fresh water to remove chlorine, salt, and sunscreen. Common mistake: leaving it rolled up in a wet towel, which can cause odors and set stains. Rinse even if you only wore it briefly.
- Hand-wash with a gentle detergent: Fill a basin with cool water and a small amount of mild detergent. Gently squeeze the suds through the fabric, then rinse until the water runs clear. Common mistake: using hot water or bleach, which can damage the sustainable materials and elastic. Never use fabric softener—it coats the fibers and reduces stretch.
- Dry flat in the shade: Lay the bottom flat on a clean towel away from direct sunlight. Turn it over halfway through drying. Common mistake: hanging it by the waistband, which can stretch it out, or drying in direct sun, which can fade colors. Avoid tumble drying completely—heat breaks down elastic.
- Store folded, not stretched: Once dry, fold the bottom and store it flat in a drawer. Keep it away from rough surfaces that could snag the fabric. Common mistake: hanging it by the straps or leaving it in a damp gym bag. Store separately from Velcro or zippers to prevent pulls.
