How Do I Avoid See-Through Swimwear When Wet?
When it comes to swimwear, no one wants a surprise transparency moment at the beach or by the pool. This guide covers exactly how to dodge that all-too-common issue of swimwear becoming see-through when wet — without sacrificing style or comfort.
Whether you're shopping for bikinis, tankinis, or a classic one-piece, we'll explore the essential features to look for: double-lined fabric, high-quality construction, textured materials, and more. You'll learn how to perform a transparency test at home, what colors work best, which swimsuit styles to avoid, and when cover-ups or extras like nipple covers come in handy.
Plus, we’ll link you to some great swimwear options from Hanna Banna Clothing — because confidence starts with pieces that are built to perform.
The Real Reason Swimwear Goes See-Through When Wet
Most people assume it's just the color or fit — but it’s usually about fabric quality and construction. Many cheaper swimsuits use thin, single-layer fabrics that absorb water quickly and stretch out, revealing more than you'd like.
To prevent this, always check if a swimsuit includes:
-
Double-lined fabric (especially in light shades)
-
Compression or moisture-resistant fabric
-
Thicker, textured material that doesn’t cling
-
A built-in swimsuit liner for extra coverage
These elements aren’t just for aesthetics — they’re what separate a beach day disaster from a carefree swim.

What Makes a Swimsuit Not See-Through?
Let’s dive deeper into the essentials of non-transparent swimwear — starting with fabric selection.
1. Look for Thicker or Textured Materials
Sheer swimwear isn’t always about color — sometimes, it’s about the weave. A ribbed or textured fabric adds visual depth and structure, helping the suit maintain swimwear opacity when wet.
Textiles that resist water absorption — like hydrophobic fabrics or moisture-resistant blends — can also offer superior coverage in and out of the water.
Consider starting with a textured tankini if you're unsure — they’re a stylish midpoint between coverage and comfort.
2. Prioritize Double Lining
This is perhaps the most important feature to check. Whether it's a swim top or a full suit, double-lining acts as a shield, making sure your suit holds its shape — and your modesty — when wet.
Swimsuits with built-in liners or support cups offer even more reassurance. Browse swim tops with structure for examples of this done right.
3. Choose Smart Colors
As tempting as a white bikini might be, light-colored swimwear (like pastels or pale tones) is more prone to transparency. If you love those shades, opt for double-lined versions — or save them for lounging poolside, not diving into waves.
Instead, dark colors and prints are naturally better at disguising moisture and maintaining coverage. Try a bold bikini in deep tones or dynamic patterns to reduce the risk.
Do the Transparency Test
Before committing to a new swimsuit, run it through a home transparency test:
-
Stretch Test: Hold the fabric gently between your fingers and stretch it. Can you see through?
-
Light Test: Place the fabric over your hand in direct light. Any outline visible?
-
Wet Test: Dab with water and hold it to the light again. Did the opacity change?
If it passes all three, you’ve got a winner.
You can also look for chlorine-resistant swimwear and UV-resistant lining, both of which preserve integrity and prevent wear that could make your suit sheer over time. These features are often found in higher-quality pieces, like those in our one-piece swimsuit collection.
4. High-Waisted Bottoms Offer Better Coverage
Low-rise bikini bottoms tend to shift with movement, which can increase the chances of fabric thinning or riding up, especially when wet. In contrast, high-waisted bottoms not only offer stylish, retro-inspired coverage but also typically feature more structured designs that resist stretching.
Try a pair from our swim bottoms collection that balances coverage with a flattering silhouette.
5. Go Seamless for a Second-Skin Feel
Swimsuits with bulky or front-facing seams can sometimes dig into the skin or create unwanted fabric bunching, especially when wet. This not only affects appearance but can lead to sheer spots around the seams.
Seamless swimwear, however, sits flat against the skin and reduces friction and fabric distortion. This creates a smoother, more secure fit, helping preserve swimwear opacity even after a full swim session.
Stylish and Smart Add-Ons to Keep You Covered
Even the most carefully selected swimsuit can use a little support now and then. Whether you're prepping for a pool party or beach vacation, here are a few bonus accessories to help you feel covered and confident.
6. Bra Cups & Nipple Covers
Some swim tops come with built-in bra cups, while others allow for removable ones. These add both shape and a visual barrier against transparency. Similarly, nipple covers (also called nipple cups) are discreet and adhesive, ideal for light-colored or thin swimwear where lining might not be enough.
Keep in mind: nude-toned options will blend best and stay invisible under fabric.
If you’re unsure whether your swim top offers this level of security, explore our swim dresses collection, where many styles include supportive elements baked right into the design.
7. Panty Liners or Silicone Concealers
These might sound unconventional, but panty liners (trimmed down) or silicone camel-toe concealers can be placed inside the lining of your suit bottoms to smooth out contours and prevent any “front wedgie” effects. This is especially helpful for one-piece swimsuits or thong styles where tight fabric may shift during movement.

Cover-Ups: Your Style + Confidence Wingman
Sometimes, the best backup plan is a great swimsuit cover-up. Lightweight, breathable, and easy to throw on, a wrap, scarf, or skirt can give you that extra layer of modesty and confidence without taking away from your style.
Whether you're walking the boardwalk or heading to grab a drink after a dip, a cover-up is your best friend — especially with light-colored swimwear.
For a complete mix-and-match moment, pair your swimsuit with one of our most popular bikinis and throw on a cover-up that complements your color palette.

Additional Tips to Avoid See-Through Swimsuits
Here’s a quick checklist for added protection:
-
Avoid applying body oils or heavy sunscreen directly before putting on light-colored swimwear. These can stain or break down fabrics.
-
Opt for quality swimwear with compression fabrics that hold their shape when wet.
-
Choose darker shades and dynamic prints over whites and pastels if you’re unsure.
-
Wash swimsuits in cold water only, and avoid wringing them out — this stretches and weakens the fabric.
-
Lay flat to dry; hanging wet suits can distort the lining and increase future transparency.

Frequently Asked Questions (FAQ)
Avoiding see-through swimwear — everything else you need to know
1. Can I add a lining to a swimsuit myself?
Yes, you can! Adding a swimsuit liner is a popular DIY fix. You can hand-sew or use fabric adhesive to attach a breathable, quick-drying lining material to the inside of your swimwear. Just make sure the fabric is chlorine- and saltwater-resistant and matches the stretch of your swimsuit.
2. What materials should I avoid when shopping for non-see-through swimwear?
Avoid thin nylon, single-layer spandex, or any swimsuit made from unlined mesh. These materials tend to become translucent when wet and often stretch too much, reducing their opacity. Stick to high-quality blends like polyester-spandex mixes with proper lining.
3. Do designer or expensive swimsuits always prevent transparency?
Not always. Price doesn’t guarantee quality. Some designer suits focus more on aesthetics than function. Always check the fabric composition, lining, and construction details before assuming it will prevent transparency.
4. Is there such a thing as water-repellent or hydrophobic swimwear fabric?
Yes. Some high-performance swimsuits are made with hydrophobic or moisture-wicking fabrics that repel water and dry quickly. These materials are more likely to retain opacity when wet and are often used in sport or competitive swimwear.
5. Does the thickness of a swimsuit mean it’ll dry slower?
Thicker fabric may retain moisture slightly longer, but well-made double-lined or compression suits are designed to dry efficiently. Look for quick-dry tags or fabric technology if drying time is important to you.
6. Are rash guards or swim shirts a good solution for avoiding transparency?
Absolutely. Rash guards are typically made from thicker, UV-resistant material and are designed to stay opaque. They're ideal for water sports and also provide added sun protection and modesty.
7. What happens to swimwear opacity over time with repeated use?
Swimwear naturally loses opacity over time due to chlorine, sun exposure, saltwater, and stretching. This can cause fading, thinning, and reduced fabric strength. Rinse with cold water after each use and avoid harsh detergents to prolong the swimsuit's life and coverage.
8. Are prints and patterns better than solids for hiding transparency?
Yes. Bold prints, darker patterns, and textured designs do a better job of disguising potential see-through areas, especially after the fabric gets wet. Patterns are also great for camouflaging moisture patches and stretch marks.
9. What is the best swimwear for plus-size or curvy body types concerned about sheerness?
Look for structured swimwear with built-in linings, compression zones, and supportive underbust features. Styles like ruched one-pieces or high-waisted tankinis with darker prints are especially flattering and effective at maintaining coverage when wet.
10. Do swim skirts or board shorts help with see-through concerns?
Definitely. These are stylish alternatives that act as built-in cover-ups, offering extra protection and peace of mind. They’re also perfect for transitioning from beach to boardwalk without needing a full wardrobe change.
