Our sizing is as easy as 1, 2, 3...
We've designed our maternity clothes in line with your pre-pregnancy clothing size for extra ease, giving you one less thing to think about. Many pieces are infused with our signature ruching and wrapping for a flawless fit at every stage.
Refer to the chart below. It's really that easy.
Take your pre - pregnancy clothing size, and look across the chart to find your Isabella Oliver size.
So, if you were usually a UK 12 before you were pregnant, just order an Isabella Oliver size 3, or if you are a UK 14, then our size 4 is for you.
If in doubt, please check against our measurement chart to find your correct size against your body measurements or contact our customer services team.
