What are the Best Maternity Jeans?

Updated 15th September 2021

This September is the 26th year of Jeans for Jeans Day   (where wearing your favourite jeans can help raise money for children with genetic disorders) so what better time than now, to buy a pair of stylish maternity jeans.

It’s estimated that one out of 25 children is diagnosed with a genetic disorder. – that’s 30,000 babies and children in the UK each year.

So far Jeans for Genes has raised over £45 million for these children so it’s really an easy way to do a lot of good (and look good doing it!)

We know it can be a little daunting to find the perfect style of jeans for your shape and tastes at any time. But throw in a growing bump and the decision can be overwhelming!

So, to make this process a little easier we’ve rounded up some of the best maternity jean styles for 2021. All you need to do is sit back and relax, we’re pretty confident there's something for everyone amongst our top 10 styles below.

What are the most comfortable maternity jeans?

Before you take a look at the different style options it’s important to decide whether you want to go for jeans that sit over or under your bump.

This will come down to personal preference (and you’ll find lots of online forums like mumsnet packed with opinions on this) but there’s lot of advice that suggests under the bump are most comfortable for early pregnancy and over the bump jeans are more comfortable later on as your bump really starts to grow.

How do you choose the right size?

Choosing your size is much easier than you think.  If you were a UK 12 before pregnancy then that’s the size to buy now. Most maternity jeans are made from soft, stretchy cotton, designed with comfort in mind.
