  How to Measure

  Use a soft tape measure, keep it snug but not tight, and measure straight across your back.

  Step 1

  Underbust Circumference

  Measure your underbust at its tightest — the circumference right under your busts.

  Step 2

  Overbust Circumference

  Measure your overbust circumference at the fullest point of your bust.

  Underbust (cm)
