Underwear Sizing

If you are new to Molke and looking for an Original or Flexi-Size bra, we always recommend using our Bra Size Calculator before using this size guide. This is the best way to get your starting size in a Molke.

If you are happy and confident in your size and unable to measure, the charts below can help you convert your size into a Molke size.

For our international friends, you can convert your international size into UK sizes with our 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.

Original Bras

The Original Molke bra is our most popular and supportive style. With no fastenings, this style goes on over your head or you can step into it. The crossover at the front means it is also perfect for nursing. This style is available from a 26-54” band and up to a UK M cup.

A few things to remember:

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.

Flexi-Size Bras

The Flexi-Size bra is more of a traditional style with adjustable straps, neckline and a hook and eye fastening. The extended hook and eye fastening means this style is also great for size fluctuations as each one covers 3 conventional band sizes. This bra was designed to be sensory-friendly so the bands, straps and seams are all super soft, whilst offering good every day support. It’s currently available up to a 54” band and UK O cup.

A few things to remember:

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.

Racerback Bralettes

Molke Racerback Bralettes offer a high level of support for a non-wired bralette and are fuller-bust friendly. They come in two styles (Mighty and Epic) so you don’t need to go up in the band to get coverage on larger chests. These bralettes make great sleep bras as well as offering comfort and containment for day-to-day wear. They are available from an XS to 7XL band (approx. UK dress size 6-40).
