Underwear Sizing

• 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.
