A word on sizing...

We recommend selecting your pre-pregnancy size for the best fit. Please note these are quite generously sized so if you are between sizes we suggest sizing down for a more fitted look or sizing up for a looser fit. 

Our model is 37 weeks pregnant and wearing a size 8 in these photos. 



It can be tricky to know what size to get when your shape is constantly changing. We want to ensure you get a perfect fit every time so have created this handy size guide to help you get it right.

Measuring bra size

If you are not sure what bra size you currently are, grab a tape measure and check out Boob or Bust who have a handy calculator, calibrated to take pregnancy and breastfeeding in to account.

This chart calculates in line with the Boob or Bust size guides rather than the bra size you wear. This is because bra sizes vary hugely between brands and we want to ensure you get the best fit every time.  At the very least we recommend choosing the size that corresponds with your under bust measurement in inches - not your bra size! 

We always recommend choosing your pre-pregnancy size for the best fit during and after pregnancy. If you are already pregnant and finding bras too tight, we'd typically suggest picking one size below your current under bust measurement and using the bra extender to the end of your pregnancy (for the best postnatal fit). 

Still not sure? Drop us an email on with your measurements and current bra size and we will get back to you as soon as we can!

I have ordered 14 and I was 10 before pregnancy. Is definitely big for me but still even if big, the zipper is to high on the top of the actual top and for a large, heavy breast is hard to get it out through the opening and a bit uncomfortable while breastfeeding.

Susan Harrison
Great top

Bought this as another layer to see me through the end if pregnancy and into motherhood.
Great feel to the fabric and a really good fit on me. Works well with the Natalactive leggings and jacket that I also bought to help me keep being outdoors during the change of seasons and shape.
Worth every penny.

I have been wearing this top from 12 weeks pregnant and it is growing perfectly with my bump. It is extremely comfortable and lightweight and washes really well.
I love that I will be able to breastfeed in this so will get great wear out of it. I have breastfed my other children and wish I had this too while feeding them as it is ideal.


This top is so soft and comfy, it feels lovely to wear! I love the thumb-holes. The bamboo helps to moderate temperature, keeping me just right whether inside or out. I would wear this top every day if I could!

Claire Dunn
So soft

Another fabulous purchase from Natal Active. The material is so soft. I'll be wearing this beyond breastfeeding.
