The Best Maternity Jeans To Wear At Any Stage Of Your Pregnancy, From A Grazia Mum

'I love shopping for jeans', said no one ever. Now imagine trying to find a pair of jeans while pregnant. Evident from the fact that the average person owns eight pairs of jeans - one for every day of the week and a spare for good luck - denim is a wardrobe staple; but when I got pregnant, I realised the old faithfuls are usually the first things to go as they’re not very forgiving. Fear not though, as there doesn’t have to be a denim-shaped hole in your wardrobe – the best maternity jeans have evolved and the choice of styles is a lot wider than it used to be. Whether you’re a fan of the best straight-leg or boyfriend jeans, I've since learnt from experience that thanks to an array of brands stepping up recently, you can be sure that finding the best pregnancy clothes doesn't have to feel at odds with your usual personal style.

When do you start wearing maternity jeans?

While no two pregnancies are the same, jeans are likely the first piece of clothing in your regular wardrobe that'll start feeling uncomfortable as your bump grows. Usually, the second trimester is when that waistband rally starts digging in and when unbuttoning your jeans is no longer reserved to post meal-times. That said, every bump grows different so listen to your body to determine when you might want to take the plunge into maternity jeans. Of course, if you're itching to hold onto your favourite wide leg jeans for longer, simply thread a hair tie through the buttonhole to loop around the button for a few extra inches for this first 12 weeks.

Should you wear jeans that go over or under your bump?

If you’ve just started shopping for maternity jeans, two new phrases you’ll pick up pretty quickly are ‘over-the-bump’ and ‘under-the-bump’. ‘Over-the-bump’ means the jeans come with an elasticated band that goes over your belly and sits under your boobs. This is designed to support the bump and give you a more streamlined silhouette. ‘Under-the-bump’ means it’s low-waisted and stops beneath your stomach.

This season’s loose-fitting, off-the-shoulder tops work well with under-the-bump denim – you can let your belly swing low without revealing too much. With more fitted tops, over-the-bump jeans are wiser as they hold everything in slightly better. Ideally, invest in both if you can – you won’t regret it.

Alternatively, while you wait for your scan, you might notice a slight swelling that stops you from doing up your jeans, but you’re probably not in ‘new jeans’ territory just yet. You can still get away with wearing your usual jeans as long as you keep the buttons undone, but if you don’t want everyone to think you’ve forgotten to do up your flies, there’s a marvellous invention called a ‘bump band’, which you can wear over your jeans and under your top to keep everything in place. It’s kind of like shapewear, but for pregnant people and without all the toilet drama.

What style of maternity jeans are best?

Maternity clothes on the high-street, as well as its denim, is fantastically priced and comes in a variety of styles, so you don’t have to spend big to get the look and fit you want. Jeans are a key wardrobe staple though, so if you do want to spend big, this is the item to do it on as the cost-per-wear makes it worthwhile. Pricier denim tends to wash better as well, which is a bonus. On the high street, Silverman's favourite pair comes from Next. Elsewhere, Seraphine has excellent designs for every style while Agolde's maternity jeans make for a great investment which'll especially come in handy if you're planning for multiple future pregnancies.

Once you’ve found the perfect pair, it might be tempting to buy them in every colour, but hold off if you can and try to only buy one pair at a time. Styles will fit differently at various stages of your pregnancy, so wait and see how your bump develops before you decide which fit to buy.

Do you buy maternity jeans in your normal size?

Even if you’ve been a size 10 all your life, maternity jeans fit differently so don’t be afraid to go up or down a size as needed. In the later stages of pregnancy all sorts of changes can happen to your body, such as swollen ankles and water retention, which can seriously mess with your sizing, so just ignore the label and pick a pair you can actually sit and eat in – you’ll want to do a lot more of that as you get further along.

How should maternity jeans fit?

They should feel secure but not in any way like they're putting pressure on you. Whether you opt for an over- or under-bump, you should feel that your maternity jeans aren't going to fall down but that they also have a fair amount of stretch. You'll hopefully find them to be much more comfortable than regular jeans, but of course, probably not as comfy as maternity leggings.

How to make maternity jeans stay up

The best way to ensure your pregnancy jeans stay where they are is to invest in an over-the-bump pair. Alternatively, you can buy separate cotton bands that you put around your waistband to help keep your clothes in place while also hiding the elasticated waist.
