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.

This bra is great I am pregnant atm and it has made wearing a bra so much more easier, no underwire but it still makes my breast look great
Megan L.
Really impressed with this bra; great quality and very comfortable.
Gemma S.
Love this bra, super comfy, loads of room to grow and shrink due to back strap. The only issue is the band at the bottom of the bra constantly rolls up which gets annoying after a while as it starts to dig in
