  • I used to dread pool days with the kids because nothing felt supportive or flattering. This swimsuit holds everything in comfortably without digging into my hips. I finally feel beautiful on the beach again.

  • Coastelle feels like high-end luxury boutique wear but flatters real, natural curves flawlessly.

    help

    How does the built-in sculpting support work?

    Coastelle swimsuits are designed with an integrated, highly breathable power-mesh lining across the midsection. This engineering provides elegant, gentle smoothing and structural hold that shapes your natural silhouette without forcing you to compromise on all-day comfort or flexibility.

    help

    Is the fabric thick, premium, and fully opaque?

    Yes. We use a premium, heavy-weight, double-lined nylon elastane blend. It is engineered specifically to ensure complete opacity (zero sheerness), even when thoroughly wet, while maintaining a smooth boutique-quality finish.

    help

    How do I choose the correct size for my body?

    We suggest selecting your standard dress size for the perfect body-contouring fit. If you prefer a more relaxed fit for casual wear or fall between sizes on our chart, we recommend sizing up one size.

    help

    What is the 30-Day Fit Guarantee policy?

    We want you to feel entirely confident in your choice. We gladly offer easy returns and size exchanges within 30 days of delivery. The item must simply be unworn with all hygienic liners and original tags fully intact.
