What is your current Band Size?

Sorry, your size couldn't be calculated

How do I measure it?

  • 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.
  • In case you do not have a tape measure, enter an approximate size of your prefered bra.

How does your band feel?

  • My band feels tight and uncomfortable
  • My band feels loose and rides up at the back
  • My band feels perfectly comfortable

Our Tip:

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

How does your cups feel?

  • My breasts are not filling the cups and there is wrinkling in the fabric
  • My breasts are fully contained within the cups
  • My breasts spill out of one or more of these areas

Our Tip:

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

How do your straps sit?

  • My straps are digging in
  • My straps sit flat on my shoulders
  • My straps slide off my shoulders

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.

We think that the best fit for you based on your answers is:

Do you know about sister size?

What bra size could also fit?

The so called sister size, sometimes also called diagonal size, of a bra is not the same size. The sister size is the next smallest or next larger bra size. It only varies in terms of a wider or tighter under bust circumference.

Tip 1

So if you feel that the under bust band is too tightyou can try to take the next size up of the under bust sizes with a smaller cup size: if your size is 36D, then size 38C has the same cup volume and a looser under bust.

Tip 2

If you think that the under bust band feels to loose, take the next smaller under bust size with a bigger cup: if your size is 40B, then the size 38C has the same cup and a tighter under bust.
