All measurements have a tolerance of +/- 0.5in.

Our models are a variety of shapes and sizes - please refer to our product descriptions for the individual sizing of each model.

All pieces run true to size, however some pieces have a more tailored silhouette, while others offer more stretch and therefore may fit differently. Some pieces have been designed to fit oversized. We would recommend, if between sizes, taking a size up.

Between sizes?

If your measurements are in between those listed in our size guide, we suggest choosing the next size up.

However, only you know what it feels like to perform your best. If you prefer a more compressive, second-skin fit, you may be better suited to a smaller size. If you prefer a fit that offers greater flexibility, choose the next size up.
