Bra sizing can seem like a bit of a mystery and our calculated size can sometimes come as a surprise.

So, what is going on? With a high proportion of women in the UK wearing the wrong size of bra, a historical issue is that many high street retailers use the ‘+4 method’ when it comes to measuring. This method takes your under bust measurement and adds on 4 or 5” (depending if it is an odd or even number) to get your band measurement. It was developed when bras were made from silk and satin and so had no stretch. Now the vast majority of bras have some sort of elastic or give in the material, and so this method is redundant and results in you wearing a bra that is too loose in the band. Why does this matter? It matters because the majority of support you get from your bra comes from the band. At Molke, we take your under bust measurement as it is and match it with the correct cup size for optimum fit, support and comfort.

In terms of cup size, if you have been wearing a traditionally measured bra, our cup size could be significantly larger. Cup sizes are not a standard size across all band sizes, so a DD cup in a 30” band isn’t the same as a DD cup in a 36” band. When you have a smaller band size, you usually have to go up in the cup size to get the same volume, support and comfort.

Our calculator size is very much a starting point. We recognise that every body is different and we all prefer different things in terms of fit, support and comfort. If you are unsure on what size you need to order, or want to check if your new bra is a good fit, please drop our expert fitting team an email at pixie@molke.co.uk and they will be happy to help.

Hi guys! I’m pregnant and have pretty hefty boobs to begin with a friend recommended you guys to me. Should I go up a cup size to account for growth or will the Flexi bras do that? Can you adjust the straps (I’m short!)? Do you normally recommend the cross over style for breast feeding?

Well I am surprised – I haven’t been measured for a long time but am roughly 36/38 and in the FF region and your calculator says my shop size would be 30 D and stellar in your range. I love firm support but think if I order this size it might not even go around….please advise….thank you

I normally wear a M&S bra size 34BorC depending on style but you calculate my traditional size as 32E and a Molke size of 34DD/E. I’m confused as I only have little boobs and I think there would be loads of empty fabric and no support. What size do recommend to give me enough support so my boobs spin round corners the same time as my torso does?

I have to get a shop bra for under a special occasion dress, so used the calculator. I’m happy in my L cosmics, which the calculator agrees with, but ordinary size is a 36G…. I own one shop bra – the one I wore at my wedding, so it’s had a single days use in its 6 year life. It is a 36F and was fitted to me for that one day…. so tried it on, expecting a massive overspill. The band fits well – so far, so good, but even after scooping every last bit of boobage possible into the cups, I’ve got a lot of storage space available 😂 i guess it would save carrying a handbag….

Hi I’m very surprised by my bra size. I’m not bothered about it being bigger as such just want the right size. Been wearing a 36D t-shirt bra from M&S. According to my measurements which I triple checked I should be a 40 FF (XL cosmic in your size) . While I admit my bras are no longer that comfortable they’re not massively tight as this would suggest they would be. I really want to get the right size but this seems quite different, is this ‘normal’? I should say as well I don’t look like I have massive boobs so again cup size a surprise.

According to your measuring guide you state I should be wearing a42 E or in your range a XL Cosmic 40F/FF.. . I am currently wearing a 42L!!!! Massive difference and I’m a tad confused…… Please advise on a possible size
