Please measure with a bra on. When measuring, you need to measure quite tight for your underbust measurement, and then over the bust, you measure loosely. Otherwise your result will be incorrect. Any questions, we're here to help.

My Necessity Bra Size Guides
Use the following size guides to fit our My Necessity Bra which is available in both regular cup and full cup sizes.
Sister sizing allows you to find your perfect fit. Sometimes after measuring yourself it is possible that your size may still need to be adjusted.
The following chart shows sister sizing for each bra size. All of the sister cups in the same row are the same size.
Sister sizing is like a seesaw. If you move up in the band, move down in the cup and vice versa. For example if you find that a size 34E fits well in the cup, but is too big around the band, go down to the next sister size in the row and try a 32F.
HM Collectives Fitting Quiz will help you find the right size. Our fitting Video is another great way to make sure you have the correct fit. Still unsure? Please email your measurements and details of how many months pregnant/feeding, we will be happy to help, we can help you avoid couriering bras back and forth. Nb. We encourage getting the size right first as it's more sustainable to send a package out once, than multiple times.

I’m a 36GG (normally) bigger just now with breastfeeding and I can wear this without feeling like I need a bra on underneath. Very supportive and very comfortable. I bought 2 as I will live in them over the summer. Even when I’m done feeding I will keep wearing them!

Supportive soft material and good fit - reminds me that high quality nursing underwear is not a luxury!!
