Maternity underwear is designed to fit your growing bump, will stay in place better and feel more comfortable than your regular underwear. What’s more, with standard undies, you may find that the waistband feels too tight or hits in an uncomfy spot as your pregnancy progresses, unlike with maternity underwear designed to grow with you. Full of fuss-free t-shirts, jumpers, dresses and trousers that are comfortable to wear, Dorothy Perkins is the perfect place to put together a no-nonsense wardrobe to perfectly complement your other bump-friendly items.

It wouldn’t be a best-of maternity list without the appearance of Seraphine.

Use your personal preference to decide between under- or over-the-bump or mid-belly styles, any will work. The Kindred Bravely under the bump underwear is SUPER comfy.

When purchasing pregnancy underwear, each brand will be different so be sure to look at the size guide. As a general rule, we recommend you should size up at least one size from your usual pre-pregnancy size, to ensure maximum comfort and a little extra room. Maternity clothes can split opinion - some say they aren't necessarily, others have a wardrobe full. It's worth noting that maternity clothes have been specially designed with the changing pregnancy body in mind, and therefore will be able to accommodate a growing bump more comfortably than regular clothes.
