Size Guidance
The recommendation module uses bust for bras, and waist plus hip for shorts and leggings.
Choose the smaller size for a closer hold, or the larger size for a softer everyday fit.
Enter Bust, Waist and Hip in centimetres, then choose Supportive, Everyday comfort or Softer fit. The tool recommends the closest available size.
Choose the smaller size for a more supportive feel or the larger size for softer everyday wear.
