Swimsuits and Care
-
Our suits come in two sizes that replace a dozen traditional ones. We call them Stretch I and Stretch II.
We use the term Stretch because the magic of our adaptable suits allows them to support multiple sizes for each unit of Stretch.
Stretch I fits UK/AUS 6-16 (up to G cup)
Stretch II fits US 18-28 (up to a J cup)
-
We produce everything in the UK — from the weaving of our unique OEKO-TEX® certified Versoform™ fabric to the production of our plastic-free and biodegradable packaging.
Our high-quality, highly adaptable swimsuits are produced at a cost many times that of a typical swimsuit. Developing, knitting, dying, sewing and packaging them takes time and care in safe, healthy work environments where wages are fair.
-
Our suits use a specially developed ribbed, seamless Versoform™ fabric made using premium quality EU-sourced, OEKO-TEX® certified nylon yarn and elastane to create a magically flexible fit that lasts.
Made entirely in the UK, sweatshop-free.
Read how it works -
Ooh, we like this question. You can find our care instructions here.
-
All of our suits offer full coverage and generally aren’t sheer, with the exception of Solar, Aster, and Yuzu, which have proven to be slightly sheer on some wearers.
We wouldn’t say it's always noticeable, but this kind of coverage will come down to personal preference.
-
No more than any other swimsuit. Our thick, flexible fabric provides plenty of coverage, but this depends on personal preference.
Our suits don’t include lining, cups or padding, as this would limit their special ability to adapt to your changing body.
-
Most likely! It’s seriously flexible — in all directions.
Many people around 6ft tall wear our one-pieces and find the fit to be super comfortable. The Poise One-Piece will offer the most adaptable fit thanks to its adjustable shoulder straps.
We’re happy to help with any sizing questions. Just get in touch.
-
Our suits don't include any built-in bust support, as this would limit their special ability to adapt to your changing body.
The super-flexible, seamless fabric adapts to fit your body and will gently hug your shape in ways a typical swimsuit wouldn't — but this kind of support will come down to personal preference.
We generally recommend our Aplomb or Verve styles for maximum support and coverage.
Stretch I supports an A-G cup (31"-41")*
Stretch II supports up to a J cup (43"-57")
* For all styles, except Poise, which will fit up to a cup D.

Restocks
-
While demand for Youswim suits might be skyrocketing, we prefer to keep our feet on the sand. We’re not a fast fashion brand and won’t endlessly scale at any cost. So, when we introduce new styles or colours, the production of others slows down. This means not all colours and styles may always be available.
