Perfect Fit


What You’ll need:

  • Your current best-fitting bra, ideally less than a year old
  • A tape measure
  • A large mirror to check that your bra fits correctly

Let’s Get Started

What is your band measurement?

  • Wrap the tape measure firmly around your underbust. Tip: Always measure in centimeters.
  • Pull it so that it feels comfortable, but not so tight that it causes discomfort.

How does your band feel?

Our Tip: For a perfect fit, a new band should be on the loosest hook and feel firm but comfortable.

How does your cup feel?

Our Tip: Your breasts should be fully contained within your bra’s cups, with no excess cleavage coming over the top

How does your straps sit?

Our Tip: Straps are at their perfect length when the breast feels supported in its natural position – usually half way between the shoulder and elbow.
