Taking Accurate Measurements
Getting the right fit starts with precise measurements. Use the table below for guidance:
| Measurement | Women's Technique | Men's Technique |
|---|---|---|
| Bust/Chest | Measure over the fullest part of your bust, keeping the tape snug but not tight | Measure across the fullest part of your chest |
| Waist | Measure at the narrowest part, just above your belly button, keeping the tape level | Measure at the natural waistline |
| Hips | Measure around the fullest part of your low hip, feet together, and tape level | Measure at the low hip area |
For one-piece swimsuits like the BetterTan Belize, don’t forget to check your torso measurement. This ensures a proper fit that provides full coverage and comfort.

- After Use: Rinse your swimsuit in cool water to remove chlorine, salt, and sunscreen. Avoid wringing it out.
- Drying: Lay it flat in a shaded area to dry.

FAQs
How do tan-through swimsuits let you tan evenly while offering some sun protection?
Tan-through swimsuits use specially crafted fabrics with micro-perforations that let sunlight pass through, helping you get a more even tan while minimizing tan lines. These tiny openings allow a substantial amount of UV rays to reach your skin, which is how the tanning effect works.
However, these swimsuits offer very little sun protection - comparable to wearing a low SPF sunscreen. To enjoy the benefits safely, consider combining them with other sun protection strategies, like applying sunscreen or limiting your time in direct sunlight.
How do I choose the right size and style of tan-through swimsuit for my body type?
To choose the ideal tan-through swimsuit for your body type, focus on styles that highlight your best features while ensuring comfort. For instance, halter tops or swimsuits with underwire are excellent for offering support to fuller busts. If you're looking for a smoother fit around the midsection, one-piece suits with tummy control panels can be a great option.
It's important to pick a swimsuit that fits snugly without feeling restrictive. Look for adjustable elements, like straps or ties, so you can personalize the fit for better support and ease of movement. If you're unsure about sizing, refer to the brand's size chart and prioritize what feels comfortable to you for the best results.
How do I properly care for my tan-through swimsuit to keep it in great condition?
To ensure your tan-through swimsuit stays in great condition, wash it by hand in cool water using a mild detergent. Steer clear of harsh chemicals, bleach, or fabric softeners, as they can weaken the fabric and reduce its ability to let sunlight through.
When it’s clean, let it air dry in a shaded, well-ventilated spot, keeping it out of direct sunlight to avoid fading or unnecessary wear. For the best results, try to limit contact with tanning oils, heavy sunblock, or high levels of chlorine. With a little care, your swimsuit can keep its unique tanning properties and last much longer.
