Frequently Asked Questions (FAQs) About Our Swimwear

Welcome to the gemmaswim.com FAQ section! We know that finding the perfect swimwear and keeping it in great condition can raise many questions. Below you’ll find answers to some of the most common inquiries about our products, sizing, care, and policies. If you need further assistance, please don’t hesitate to reach out through our website’s contact form.


1. What makes your swimwear different from other brands?

Our swimwear is designed with a focus on quality, comfort, and durability. We use premium fabrics that offer excellent stretch, shape retention, and resistance to chlorine, saltwater, and sunscreens. Every piece is carefully crafted to provide a flattering fit that moves with you—whether you’re lounging by the pool, surfing waves, or doing laps. We also prioritize timeless styles and versatile cuts, so you can enjoy your favorite pieces season after season.

2. How do I find my correct size?

Choosing the right size is crucial for both comfort and confidence. We recommend consulting our detailed size chart, which you can find on every product page. To get accurate measurements, use a soft tape measure and follow these steps:

  • Bust: Measure around the fullest part of your chest, keeping the tape parallel to the ground.
  • Waist: Measure around the narrowest part of your natural waist.
  • Hips: Stand with your feet together and measure around the widest part of your hips and buttocks.

If your measurements fall between two sizes, we generally suggest sizing up for a more relaxed fit or down for a tighter, more compressive feel—depending on your preference. Keep in mind that our fabrics are stretchy but designed to fit snugly for secure wear in water.

3. Do your swimsuits offer good bust support?

Yes, many of our styles include thoughtful support features. For tops, you’ll find options with removable padding, adjustable straps, underwire, or built-in shelf bras depending on the design. High-neck tops and full-coverage backs also provide extra security. For larger busts, we recommend looking at our styles labeled “maximum support” or those with wider straps and higher side coverage. If you have specific concerns, feel free to check individual product descriptions for support level details.

4. Are your products sustainable or eco-friendly?

We are committed to reducing our environmental footprint. Our swimwear is made from recycled materials—such as regenerated nylon from ocean waste and post-consumer plastics—without compromising on quality or performance. The fabrics are also produced using eco-conscious manufacturing processes that minimize water and energy usage. Additionally, our packaging is plastic-free and recyclable. While we continue to improve our sustainability practices, we believe in creating swimwear that you can feel good about wearing and wearing again.

5. How should I care for my swimwear to make it last?

Proper care extends the life of any swimsuit. We recommend these simple steps:

  • Rinse immediately after use: Rinse your swimwear in cold fresh water to remove chlorine, salt, sand, or sunscreen. Avoid leaving it rolled up wet for long periods.
  • Hand wash gently: Use a mild soap or specialized swimwear wash. Never use harsh detergents, bleach, or fabric softeners.
  • Avoid machines: Do not wring, twist, or put your swimsuit in the washing machine or dryer. The agitation and heat can break down elastic fibers.
  • Dry flat: Lay your swimsuit flat on a towel away from direct sunlight or radiators. Hanging can stretch the fabric, and direct heat can fade colors.
  • Rinse after each wear: Even if you haven’t been swimming, sweat and body oils can degrade the material over time.

6. Can I return or exchange an item if it doesn’t fit?

Absolutely. We want you to love your purchase. If for any reason you’re not satisfied, you may request a return or exchange within a reasonable period after delivery (please refer to our Returns Policy page for the exact window). To be eligible, items must be unworn, unwashed, and with all original tags attached—including the hygiene liner. We do not accept returns on swimwear that has been worn without the protective liner or that shows signs of use. Exchanges are processed quickly, but note that return shipping costs are generally the customer’s responsibility unless the item arrived defective or incorrect. Refunds are issued to your original payment method once we inspect the returned product.

7. What if I receive a defective or damaged item?

We take quality seriously, but occasionally issues slip through. If you receive a swimsuit with a manufacturing defect (e.g., loose stitching, broken clasp, color flaw) or damage from shipping, please contact us within a few days of delivery. We will ask for a clear photo of the problem and your order number. Once verified, we’ll arrange a free replacement or a full refund—no extra cost to you.

8. Do you offer international shipping?

Yes, we ship to many countries around the world. When you enter your shipping address at checkout, available options and estimated delivery times will be shown. Please be aware that customs duties, taxes, or import fees may apply depending on your country’s regulations; these are not included in our prices and are the buyer’s responsibility. We advise checking with local customs for details before placing an order.

9. How can I track my order?

After your order is dispatched, you will receive a shipping confirmation email containing a tracking number and a link to the carrier’s website. You can use this to see real-time updates on your package’s journey. If you don’t see the email within a few days, please check your spam folder or log into your account on gemmaswim.com for tracking information.

10. Do you restock sold-out styles?

We often restock popular styles, but not all designs are continuously produced. If an item you love is sold out, you can sign up for the “notify me when available” option on the product page. You’ll receive an email as soon as it’s back. For limited-edition collections, we may not restock once they sell out, so we recommend grabbing your favorites early.

11. Can I wear your swimwear for intense activities like surfing or volleyball?

Yes, many of our styles are designed to stay in place during active use. Look for features like high-back coverage, adjustable ties, racerback straps, or secure hook-and-eye closures. However, for very high-impact surfing, we suggest choosing a full-coverage one-piece or a top with a chest zip or sturdy clasps. Always refer to the product description—if a style is marked “for light lounging only,” it may not hold up to rough waves.

12. Are your colors and prints true to the photos?

We strive to display our products as accurately as possible. However, different computer monitors, phone screens, and lighting conditions can cause slight variations in color. The fabric sheen (matte vs. shiny) may also appear different in real life. If you are unsure about a shade, please read customer reviews or ask us for a second opinion via our contact form—we’re happy to help.

13. What if I have an allergy to certain materials?

Our swimwear is primarily made from nylon/spandex blends (including recycled versions) and polyamide. These are hypoallergenic for most people. If you have known sensitivity to elastane, spandex, or nylon, we recommend checking the fabric composition listed on each product page. We do not use latex or nickel in any of our hardware. For severe allergies, always do a patch test by holding the fabric against your inner arm for a few hours before wearing the swimsuit in water.

14. Can I mix and match different sizes for tops and bottoms?

Absolutely. We understand that many people need different sizes for their top and bottom. Simply order the top in your bust size and the bottom in your hip/waist size. There is no requirement to purchase a matching set. If a particular print is available as both a top and a bottom, you can select each separately. For bikini sets listed as a single item, please check if the listing allows size variations—if not, you may need to add individual pieces to your cart.

15. How do I remove sunscreen or tanning oil stains?

Oil-based sunscreens and tanning oils can leave marks on swimwear. To remove them, gently dab the stain with a mild dish soap (not laundry detergent) before rinsing. Alternatively, use a specialized stain remover for synthetic fabrics. Avoid rubbing vigorously, as that may damage the material. After treating, hand wash as usual. To prevent future stains, try to apply sunscreen at least 10–15 minutes before putting on your swimsuit, and choose mineral-based sunblocks when possible.
