Measuring Tips
Here are some tips to help you order the correct size. If you don’t have a measuring tape, no problem! Use a piece of string or ribbon to mark the measurement and then hold it alongside a ruler or yard stick to find the measurement.
Bust
Lift your arms slightly and measure around your body (without a shirt is best), crossing over the fullest part of your chest.
Waist
Measure around the natural waist, where you normally wear your pants, shorts or skirt.
Hips
Stand with your heels together and measure around the fullest part of your hips.
Frequently Asked Questions (FAQ)
Many terms and abbreviations are used when it comes to sun protection: Sun Protection, SPF, UPF, UVA, UVB, anti-UV. If you’re feeling confused, don’t worry — here are simple answers to the most common questions.
SPF (Sun Protection Factor) refers to the level of protection against sunburn caused by UVB rays (ultraviolet B radiation). This term is commonly associated with sunscreens and cosmetic products. The number next to SPF indicates how effectively the product protects your skin and how long you can stay in the sun without burning.
UPF (Ultraviolet Protection Factor) is the sun protection rating used for fabrics. It shows how much UV radiation can penetrate through the material and reach your skin. For example, a UPF 50+ rating — the highest available — means that only 1/50th (or 2%) of the UV rays can pass through the fabric. UPF ratings are assigned by certified laboratories after testing the fabric using professional equipment that simulates sunlight.
SPF (Sun Protection Factor) is mainly used for sunscreens and cosmetic products.
UPF (Ultraviolet Protection Factor) measures the sun protection level of clothing and fabrics.
While both indicate how long you can stay in the sun without getting burned, there’s a key difference:
SPF typically refers only to protection against UVB rays, which cause sunburn.
UPF measures protection against both UVA and UVB rays, offering broader coverage.
Ultraviolet (UV) radiation from the sun that reaches Earth is made up mostly of UVA and UVB rays.
UVA rays make up about 95% of the UV radiation that reaches us. They’re present all year round and can penetrate clouds, glass, and deep into the skin. You don’t feel them immediately, but over time they cause skin aging, pigmentation issues, sun sensitivity, and can contribute to skin cancer.
UVB rays make up about 5% of UV radiation. They carry more energy and are mostly responsible for sunburns and tanning. Some UVB rays are blocked by clouds and glass, but they still penetrate the upper layer of the skin. While UVB is what gives you a tan, it can also cause burns, eye irritation, allergic reactions, and increase the risk of skin cancer.
There’s also UVC radiation, which is the most dangerous type — but luckily, it’s completely absorbed by the ozone layer and doesn’t reach Earth’s surface.
That’s why it’s essential to protect your skin from both UVA and UVB rays.
It’s important to understand that there’s no one-size-fits-all answer. The “right” level of sun protection depends on many personal and environmental factors — your skin tone (light or dark), how your skin reacts to heat and sun, any allergies or sensitivity, the time of year, weather conditions, how intense the sun is, and what you’re planning to do (sunbathing, swimming, staying in the shade, etc.). Only you can choose the right level of protection for your skin and situation.
SPF Levels (used in cosmetics and sunscreens):
SPF 4–10 – Moderate protection
SPF 10–20 – High protection
SPF 20–30 – Intensive protection
SPF 50 – Maximum protection
UPF Ratings (used in clothing and fabrics):
UPF 5–19 – Moderate protection (blocks 80%–94.9% of UV rays)
UPF 20–29 – High protection (blocks 95%–96.6%)
UPF 30–49 – Very high protection (blocks 96.7%–97.9%)
UPF 50+ – Maximum protection (blocks 98% or more)
The higher the number, the more UV radiation is blocked — but the best choice depends on your individual needs.
Yes, it does. All other factors being equal, darker or more vibrant colors absorb more ultraviolet radiation than light or pale colors. The more UV rays the fabric absorbs, the less reaches your skin — meaning better sun protection.
For example, a bright yellow swimsuit with raspberry flowers and blue seashells in the print will generally offer more protection than a plain light beige swimsuit. So, color isn’t just about style — it also plays a role in sun safety.
It’s a next-generation material, specially developed for swimwear and beachwear. The fabric is a mesh constructed using a unique fiber-weaving technology that creates a surface filled with microscopic pores.
Each honeycomb-like cell is designed to let sunlight through while blocking harmful UV radiation. This innovative structure allows for tanning while protecting your skin.
Bip Bip Beachwear #SPF fabric has undergone professional laboratory testing, and its protective properties have been confirmed to be equivalent to SPF 35 sunscreen.
Bip Bip Beachwear #SPF swimsuits fabric are virtually non-transparent, thanks to the unique fiber-weaving structure and carefully chosen prints and colors.
However, there’s an important detail to note: the fabric is thin and breathable due to its porous design, so transparency may slightly increase when the material is stretched tightly over the body. That’s why it’s essential to follow the size guide and choose the right fit for your body to ensure both comfort and proper coverage.
To preserve the fabric’s micro-porous structure and prevent fiber deformation, it’s important to avoid excessive stretching. Always refer to the size chart and choose a suit that fits comfortably — not too tight, no rubbing or compression.
After swimming in salt water, rinse the swimsuit in cool, fresh water without detergents.
Because Bip Bip Beachwear #SPF fabric contains no natural fibers, it doesn’t absorb odors or pigments, so frequent washing is not necessary. For occasional cleaning, use a mild soap solution and water no warmer than 30°C. Hand washing is recommended, or use the delicate cycle on a washing machine with a laundry bag.
Avoid whirlpool jets and extreme temperature changes — saunas and hot baths can damage the fabric.
Longevity depends heavily on proper care. While most swimsuits are designed to last one season, you can extend the life of your Bip Bip swimsuit with the right maintenance.
Even the highest-quality swimwear can lose shape or wear out prematurely due to exposure to sunscreens with UV filters and other external factors.
The golden rule: never leave your swimsuit wet and crumpled. Always follow the care instructions carefully — that’s the key to keeping it in great condition for more than just one summer.
Wearing a Bip Bip Beachwear #SPF swimsuit with sleeves allows you to stay in the sun longer than with regular swimwear. However, we do not recommend prolonged sun exposure — even with full protection, your body can still overheat from intense sunlight.
The Bip Bip Beachwear #SPF fabric offers sun protection equivalent to SPF 35 sunscreen, but keep in mind: the effect varies depending on your skin type and tone. Always listen to your body and stay mindful of the heat.

- Wash your Bip Bip Beachwear as soon as possible after they’ve been worn. If for whatever reason you cannot wash your garment(s) right away, a rinse in cool water is better than no rinse at all.
- Bip Bip Beachwear should not be machine washed! Hand wash in cold water on gentle cycle with a mild soap/detergent. Aggressive wash can damage your swimwear, leaving it stretched out, or otherwise ill-fitting.
- Do not wring out your Bip Bip Beachwear, but instead lay it flat to dry out of direct sunlight.To speed up the drying process, roll your garment in a dry, clean towel, pressing down gently to absorb excess water.
- Do not bleach, dry clean, or iron your Bip Bip Beachwear.
- Only store your Bip Bip Beachwear when they are completely dry.
- Remove sand grains by shaking your Bip Bip Beachwear outside. Be sure to turn it inside out and gently brush with your hand to remove hidden sand particles. After removing what you can this way, rinse your garment in cool water and lay it flat to dry.
- Avoid sitting on or rubbing against rough surfaces, such as concrete and swimming pool decks, as these surfaces can snag the material of your garment. If you need to sit, lay a towel or blanket down, or an article of clothing that you aren’t worried about snagging.
- To minimize fabric damage and color loss – keep in mind, excessive heat and high chlorine levels can breakdown the fibers of your garment, even in chlorine resistant fabrics.
- Apply any sunscreens, lotions, and deodorants 15-25 minutes prior to putting on your Bip Bip Beachwear to avoid staining or discoloration of the fabric.
