The measurements presented are for guidance only and are based on body measurements. Actual fit may vary depending on garment cut and desired style. For optimal choice, trying on is the best option.
Castelli uses Italian/European sizing, which is generally more fitted than North American standards. If you are between two sizes or prefer a looser fit, we recommend choosing the next size up.
