Choosing between tan-through vs regular swimwear comes down to one simple question: do you want your swimsuit to help you tan, or to block the sun entirely? Tan-through swimwear is made from a fine, breathable fabric that lets a portion of sunlight pass through the material, so you can top up your tan while staying covered. Regular swimwear uses a denser, opaque fabric that keeps the sun off the skin underneath. Both have their place, and the right choice depends on how you like to spend your time in the sun. Below we compare the two across the things that actually matter on holiday.
How tan-through and regular swimwear differ
The key difference is the fabric. Traditional swimwear is woven or knitted to be completely opaque, which is why you're left with sharp tan lines wherever the fabric sits. Tan-through fabric is engineered with thousands of tiny perforations that are invisible to the eye but allow sunlight to filter through. The result is a softer, more even tan with far less obvious lines, without having to go without a swimsuit. The fabric is also lighter and dries faster, which many people find more comfortable in the heat.
Tanning results
This is where tan-through swimwear really stands apart. Because light passes through the material, the skin beneath tans gradually alongside the areas left bare, so you avoid the stark white patches that regular swimwear leaves behind. Regular swimwear, by contrast, fully blocks UV under the fabric, which is exactly why tan lines form. If a smooth, all-over glow is your goal, tan-through is the clear winner. If you'd rather keep certain areas pale, a regular opaque suit does that job.
Coverage and confidence
A common worry is that a fabric which lets light through must be see-through. It isn't. Quality tan-through swimwear is designed to stay opaque to the eye while still transmitting sunlight, so you get full coverage and full confidence. Our Black & Gold one-shoulder swimsuit is a good example: a bold, statement piece with a flattering cutout that looks every bit as polished as a regular suit.

Comfort and feel
Tan-through fabric tends to be lighter and more breathable than heavier conventional swimwear, and it dries noticeably quicker after a dip. That makes it a comfortable choice for long, hot days by the pool or on the beach. Regular swimwear can be more structured and supportive in some styles, so if you prioritise firm sculpting over breathability, that's worth weighing up.
Care and longevity
Both types last longest with gentle care: rinse in cool water after swimming, hand wash, and dry flat away from direct heat. Tan-through fabric is delicate by design, so avoid wringing it or leaving it screwed up in a damp towel. If you look after either style properly, it will hold its shape and colour season after season.
Sun safety comes first with either choice
This is essential: tan-through swimwear offers only partial sun protection, and it is not a substitute for sunscreen. Because sunlight passes through the fabric, the skin underneath can burn just like exposed skin. Always apply a broad-spectrum SPF sunscreen over your entire body, including the areas covered by your swimsuit, and reapply regularly, especially after swimming or towelling off. Avoid the sun during the hottest part of the day, typically late morning to mid-afternoon, seek shade, and never use tan-through swimwear as an excuse to stay out longer. A gradual, protected tan is always the healthier one. Regular swimwear blocks more sun under the fabric but still leaves plenty of skin exposed, so the same sunscreen rules apply.
So which should you buy?
If you love the idea of a more even, natural-looking tan with fewer harsh lines, and you want lightweight, quick-drying comfort, tan-through swimwear is the standout choice. If you specifically want to keep areas of skin fully shaded, a regular opaque suit may suit you better. For most sun lovers, tan-through delivers the best of both worlds: full coverage plus a smoother tan. Ready to make the switch?
