If you are new to Molke and looking for an Original or Flexi-Size bra, please use the Bra Size Calculator before using this size guide.

The size generated with the calculator is just a starting point. If you like a firmer fit in the band, you could try the next band size down, but please remember to size up in the cup if you do so.

If pregnant and pre-36 weeks, you may wish to go up in the band size for extra comfort as your ribs expand.

If breastfeeding and feeding a newborn or experiencing a lot of fluctuation throughout the day in breast size, then please try and measure at your fullest point in the day.

If you know your international size and would like to convert it to UK sizes, we have handy cup and band size conversion charts.

If you are unsure on sizing or in need of any fitting help, then please contact us.  We also have a little more about sizing in this blog post.
