Tips on how to take the perfect measurements

  • Wear a T-shirt bra without padding.
  • Adjust the straps so that the tip of your breast – as seen from the side – is in the middle of the cup.
  • Have a friend help you with the measurements.

Step 1: Take your underbust measurement

Step 1: Take your underbust measurement

1. Place the measuring tape flat against your skin – directly under your breasts. Make sure that the tape runs horizontally around your torso and is at the same height under your breast as on your back. Allow your arms to hang down naturally and breathe as usual.

2. Tighten the measuring tape a little and round the measurement up or down to the next full number. (Example: Round up to 73 cm if you have measured 72.8 cm or round down to 72 cm if the measurement shows 72.2 cm)

3. Move the slider to that position.
