Women's Castelli sizing is based on your physical measurements and each garment's intended use.

Racier items are designed to use fabric stretch to achieve a very snug fit, as such physical garment sizes may vary within the range. Please do not compare sizing with other manufactures.

Please note that the sizes shown above represent the maximum size for the garment, so someone with a 88cm bust would be a size M or if you have a 91cm bust you are a size L. You do not need to size up for jackets or vests.
