Why Reading Swimwear Labels Is Essential
You might not realize it, but swimwear labels are a goldmine of useful information. Far more than just a size number, they detail the fabric composition, washing instructions and sometimes the level of sun protection and more.
Understanding these labels is the key to making the right choice for your needs during your next purchase. Knowing what these indicators mean will help you find the correct size and fit, even across different brands.
Before packing your new swimsuit in your suitcase or jumping into the pool, it’s crucial to read the label carefully. It will help you preserve your swimwear longer by maintaining fabric quality and colour vibrancy and prevent care mistakes that could damage it after just a few washes.
How to Decode Swimwear Labels
How to Decode Swimwear Labels
Swimwear labels include various types of information, often in the form of text, symbols or codes. First, you'll find the fabric composition, which tells you what materials were used, crucial for understanding stretch, chlorine resistance or drying speed.
Next are the care instructions, represented by universal laundry symbols. These are essential to avoid damaging the fabric. UV protection is also often indicated with a UPF rating, which shows how effectively the fabric blocks ultraviolet rays.
Of course, sizing is also listed, sometimes using different systems depending on the country. You may also find details about the cut or support level, depending on the swimsuit model.
The fabric: understanding swimsuit materials
The fabrics used in swimwear directly impact durability, stretch and comfort. Here are the most common materials:
- Nylon: Very soft, lightweight and fast drying. Perfect for optimal comfort.
- Elastane (Spandex): Offers excellent elasticity, ensuring good support.
- Polyester: Chlorine-resistant, retains colours well and lasts longer.
- Technical blends: Some swimsuits include special fibers to enhance resistance to UV rays, salt or sand.
Sizing and fit
Size can vary depending on the brand or country. Always check the size guide to avoid surprises. Key things to keep in mind:
- Sizes are often listed using different systems (Canada, US, Europe, France, etc.). Always compare size equivalents to find your best fit.
- Coverage and cut types:
For bikini tops, sizing is based on bust measurement combined with cup size, ranging from A to D, D+ and up to F depending on the model.
| Coverage | Cut Examples | Description |
|---|---|---|
| Light | Bandeau, triangle | Minimal coverage, ideal for tanning and a lightweight feel. |
| Medium | Push-up, bralette, cropped tankini | Balanced support and coverage, comfortable for everyday wear. |
| High | Long, flowy or ruched tankini, rashguard | Maximum coverage, ideal for sun protection or active use. |
For bikini bottoms, the size corresponds to a hip and waist measurement and varies between low, medium and full coverage, with notable differences depending on the cuts offered.
| Coverage | Cut Examples | Description |
|---|---|---|
| Light | Cheeky, low-rise, thong, hipster | Minimal back coverage, leaving more skin exposed. |
| Medium | Brazilian, classic bikini, high-waisted | Moderate back coverage with partial exposure. |
| High | Boyshort, swim skirt | Full back coverage, ideal for more support and comfort. |
Support and fit: presence or absence of underwire, removable pads, adjustable straps, etc. These elements influence the fit and shape and allow the swimsuit to adapt to your figure for optimal comfort.
Care instructions
Labels typically include several textile care symbols. Understanding them is key to know how to care for your swimsuit and prolonging is life. Here's what the most common symbols mean:
| Symbols | Meaning | Why It Matters | What To Do |
|---|---|---|---|

 |
Do not tumble dry | Excessive heat can alter the fabric’s shape, colour and flexibility. | Always air dry your swimsuit. |

 |
Do not iron | Heat can melt or warp synthetic fibres. |
* Note: Symbol designs may vary slightly depending on the brand.
UV Protection and technical caracteristics
Modern swimwear is more than just stylish, it’s packed with technical innovations for comfort, protection and longevity. UV protection, for example, ensures the fabric blocks up to 98% of harmful ultraviolet rays.
Other technical features such as chlorine resistance, moisture-wicking, quick-drying or compression fabrics address specific needs, whether for sports performance or daily comfort.
The rise of recycled fibres also reflects an increasing demand for environmentally friendly options.
| Feature | Meaning | Impact | Ideal For |
|---|---|---|---|
|
High UV protection | Effectively protects the skin from harmful UV rays. | Choose these models for long sun exposure. |
|
Eco-friendly material | Reduces the environmental impact of your swimsuit. | Opt for these models for a more sustainable choice. |
|
Chlorine-resistant | Allows pool use without rapid fibre degradation. | Ideal for frequent swimmers; rinse well after each pool session. |
|
Moisture-wicking or quick-drying | Dries faster, reducing wetness after swimming. | Best for comfort, especially with intensive or frequent use. |
|
Compression fabric or lining | Enhances body shape and support during physical activity. | Choose this fabric for a better fit and optimal comfort in motion. |
