Union Jack Maternity & Postnatal Leggings


Need some help? Find your fit.

We are unashamed Royalists at Natal Active HQ and we are so excited about this year's Jubilee that we have launched a new British Made activewear set with an abstract Union Jack print to celebrate!

These squat proof leggings that are fit for a queen have been designed to see you through every step of your pregnancy, or wear as a postnatal, high waisted legging. The print has been designed by a British Fabric designer, the fabric milled and printed in the UK and the leggings have been made by a fantastic women-led manufacturer in the North East. Plus coming from your favourite British maternity brand, what more could you want!

As these leggings are being made to a limited edition production run, we are now taking pre-orders. The product will be shipped by the end of May

  • Soft, wicking fabric
  • Wear high and low waisted
  • Suitable for both during and after pregnancy
  • Totally squat proof
  • Deep pockets on both sides
  • Full length


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 help@natalactive.com with your measurements and current bra size and we will get back to you as soon as we can!
