Size Chart

Fit & Sizing Notes
Our swimwear is designed with a petite-first fit and follows true, traditional swim sizing (not vanity sizing).

Why Height Matters
Height and torso length affect how swimwear fits. Taller frames may require additional rise even at the same numeric size.

If you are tall (5’7”+), have a long torso, or prefer more front coverage, we recommend sizing up or requesting added front height for bottoms on made-to-order styles.

Our XS and S run intentionally small and are best suited for customers who prefer a minimal, low-cut fit.

If you are between sizes or unsure, we are always happy to help guide you to the best fit.

It's important to keep in mind that the size chart provided is just a guide and that everyone has their own coverage preference. Some customers may prefer a smaller size for minimal coverage, while others may want more coverage and choose a larger size. It's also possible to customize the fit of certain items, such as adding front height on bottoms, adding side length if you have bigger hips yet prefer smaller coverage, or requesting tie sides. 

When it comes to top coverage, personal preference plays a big role. Even if someone is a 32D, they may still prefer a smaller size to show underboob or to have minimal coverage. If you have any questions about sizing or would like to request a custom item that isn't listed on our website, you can contact us through email at info@nsaswim.com or the form submission on our website, and we will respond within 24 hours.
