But don’t forget, your maternity style is totally down to you. Should I size up in maternity clothes? Or do you buy the same size in maternity clothes?

Your maternity size is likely to be around the same size as you were pre-pregnancy - most brands recommend choosing the same size in maternity pieces. So, if you wore a size 10 in jeans pre-baby, you'll probably be fine to wear a size 10 in maternity jeans when you're expecting. Of course, it's a bit of trial and error – but maternity sizes are generally the same as non-maternity sizes, just with extra panels or adjustment to fit around your bump and growing baby.

H&M Pregnancy Clothes Anyone who has carried a baby knows very well that it often isn't just your tummy that grows; your whole body can change when you're carrying a child - in the most amazing ways, of course.

Any excuse to treat yourself when you're carrying new life, right?Buy maternity clothes that make you feel ‘like you’: Just because you're becoming a mum doesn't mean you need to totally reinvent your personal style. As founder and creative director of Beyond Nine, Naomi Raybould, explains: “At a time when your body is rapidly changing and it may not quite feel like your own, keeping your identity via the way you dress is a worthy investment. The bonus of shopping this way, is that you'll want to continue wearing the clothes long after your baby is born too. The ultimate compliment for me is when a customer pulls on an item of our clothing and tells me they feel like themselves in it.” Shopping for maternity fashion can be a bit of a minefield, but it also provides the perfect opportunity to jazz up your wardrobe with some new pieces (as well choosing investment staples you'll wear way beyond the birth of your baby).
