Find the best size for you


  1. What’s your pre-pregnancy size?

We’ve designed our collection based on women’s standard dress sizes BUT with boobs and bumps in mind. So if you’re normally a size 12, it’s most likely that you’re a size 12 here too. We fit our styles on a C-D cup bust and we always test on a range of bodies to understand how things work on a range of shapes.


  1. We put fitting tips in the product description

Having been pregnant ourselves, we know how things can change (sometimes dramatically!), so we’ll always give tips as to the fit of each garment in the product description. Some things have been designed to be loose and floaty, others to hug your curves. You might decide to size up or down based on how you like to wear your clothes, or how you’re feeling at the moment. We’re always happy to give you advice if you’re not sure!

Also, check the product description for the model’s measurements too. We aim to use pregnant models whenever we can, so we’ll give her height, size and months pregnant to help you understand the fit.

These are the measurements our patternmakers use to create each Maive & Bo garment. Find yourself here to double check your size against ours.

Still not sure? Get in touch! Email us at with your size/measurements and the style you’re interested in and we’ll be happy to advise you. Don’t forget, our easy returns policy means you can also exchange a size if it isn’t quite right.

Simply find your pre-pregnancy size in the chart below. Our maternity dresses have been designed based on standard dress sizes, with a little extra room added for boobs and bumps.

Everyone is different and some people change a lot during their pregnancy and afterwards. If you're not sure use your current bust size to find your Maive and Bo size. We also add little notes about the fit on every product page. And if you're still not sure - just ask us!
