Size Chart

Our Premium Ready-to-Wear collections are made with luxuriously soft and supple limestone-based Yamamoto Neoprene (2.5 mm thick) and high-quality, 4-way stretch Lycra fabric. Together with our exceptionally tailored design, these materials provide added stretch and a flexible, forgiving fit.

What's more... our signature side-ties allow for greater variance in bottom sizing: cinch tighter or loosen as needed for a more customized fit.

Notes:  The cm ranges above are averaged across multiple collections with slightly different fits. Collection-specific size charts are provided on each product page.

  • The cm ranges presented above estimate the minimum and maximum body measurements expected to comfortably fit in a given size, and are based on actual wetsuit measurements and stretch capacity.  
  • For example, with the XS Bust range of 69-79cm: 69cm is just slightly larger than the actual wetsuit measurement (you want it to stretch for a snug fit), and 79 cm is at the upper end of the materials' stretch capacity.  
  • For an optimal fit, your measurements should be somewhere within the given range, but larger measurements may still fit if you are smaller in other areas.
  • S+ and M+ are our tall/longer torso sizes. Ladies who fall in the XS, L, and XL size ranges may want to choose a larger size to accommodate additional length/height.  Our jackets provide an option for those with a hard time fitting in a 1-piece suit.

While measurements are more specific, we have also done our best to translate our sizes in to standardized sizes you may be familiar with for the following countries:

It is important to remember that every woman's body is different, and our wetsuits stretch in subtle ways to fit differently based on height and weight distribution, as well as specific measurements.
