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.

Really sexy...only nursing bra I feel fab in! I cut off the cross over straps at the front as they were loose on my chest bone. The back detailing is beautiful.

Good quality. Lovely colour
Amy B.
Beautiful and elegant maternity bra. They are comfortable and fit amazing.

This bra is great! Its super comfy while being sexier than most breast feeding bras / it also gives great shape. The magnetic clips took some getting used to as they seem rather stiff to start with, but I am delighted with the bra all in all- one of the nicest breastfeeding bras I’v seen.

I love this bra, it is by far the loveliest and best designed nursing bra I have ever worn. The magnetic traps are genius! And It doesn’t look like a nursing bra it isn’t mumsy and unattractive like most other nursing bras. Only issue I have is the difficulty of getting it on and off.
kye c.
was nice to find something sexy for my partner, she felt comfortable wearing it also, which is good.
Laura G.
A beautiful product! Looks fab on and is very supportive. Fairly straightforward to undo the clips one handed when for feeds.
The only problem is the under bust fabric cuts in after a long day of use .
Malwina W.
I would like to buy this bra in size 34h like I bought in black , Please make it in bigger size
Taryn S.
Feels beautiful and fits perfectly.
Charlotte a.
I am 32FF in hotmilk bras, but needed 32G in this as the cups aren't that big.
The only complaint is the padding doesn't cover enough boob. My nipples aren't inside that section.
Bad design, pretty bra though
Mollie S.
Fits beautifully and is comfortable. Magnetic clasps make feeding super easy. Sometimes the halterneck straps rub & it is hard to wear tops were the bra isn't seen.
Carrie N.
Love this bra! It’s supportive, shapes well, fits well, and has a really strong magnet clip. It’s nice to feel sexy in lingerie after mom-hood struck!
Julia S.
Gorgeous sexy bra. Wonderful fit. Sizing runs small.
Barbara K.
Super comfy and really pretty! Amazing customer service across the whole delivery and returns process!
