Wearing ill-fitting apparel can be uncomfortable or not provide the expected support, which can negatively impact performance.

Choose the right size for you to achieve the best fit.


1. Check the size chart
Always check the size chart on the product page and choose the one that matches your body type.

2. Compare with apparel you already own
If actual measurements are listed, comparing them to well-fitting apparel you already own can make it easier to understand.

3. Is it better to be too large than too small?
We feel that many customers order larger sizes because it is an online store.

Sports bras and leggings perform best when they fit snugly, so if you're unsure, it's best to choose the smaller size.

4. I want help choosing a size
