How to Measure

  • Chest: measure horizontally under the arms around the fullest part of the chest.
  • Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
  • Hips: measure horizontally around the fullest part of the hips with feet together.
  • Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
  • Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.
  • Bra: measure bust at the fullest point and underbust directly below the bust.
Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
