Soft maternity knickers that sit low, under your bump

Early in pregnancy it's your hips that change, and later the bump takes over the front. These sit low, with a soft crossover waistband that stretches with your hips and then rests under the bump without pressing on it.

They're 71% Tencel™ Modal, soft and light, with no tags and no bulky seams, and they sit smoothly under leggings and dresses.

The gusset has three layers for the discharge and little leaks pregnancy brings, from a sneeze to a long day on your feet.

Being low and light, they're cooler than an over-bump pair, which helps in summer. Buy one pair to try, or a pack of two, three or five.

Questions, answered.

What size should I order?

Use the size guide with your usual dress size from before pregnancy: S is 6 to 10, M 10 to 14, L 14 to 18 and XL 18 to 22. They come up small, and a few people have found them tight going by the guide, so if you're between two sizes, take the bigger one. Knickers can't be returned once they're opened, for hygiene reasons, so it's worth a minute with the guide first.

Should I choose under-bump or over-bump?

Under-bump sits lower and is cooler, which many people prefer earlier in pregnancy and in warm weather. Over-bump covers the bump and keeps it warm, which tends to suit later pregnancy and winter, and plenty of people have both and switch as the bump grows.

When should I switch to maternity knickers?

When your usual knickers start to dig in at the waist or leave marks. There's no set week, and because these stretch with your hips, you shouldn't need a bigger size each trimester.

Can I wear them after a C-section?

Not straight away. They sit low, close to where a C-section scar usually is, so for the first weeks our high-waisted Postpartum Knickers are the better choice. Once you've healed, these are comfortable again.

What does the gusset cope with?

Discharge and light leaks in pregnancy, like the ones a sneeze or a cough can bring. It isn't made for the heavier bleeding after the birth; our Postpartum Knickers have a gusset designed for that.

Customers say these knickers are incredibly soft and comfortable, with a high waistband that sits perfectly above the scar without rolling or digging in. The fabric feels gentle on sensitive skin and maintains its shape after repeated washing. Many reviews highlight the thoughtful design that provides good coverage while feeling light and supportive. Users appreciate the quality construction and practical fit for both pregnancy and recovery. Some note the sizing runs slightly snug, and one mentioned the fabric picks up lint occasionally. Overall, customers find these a worthwhile investment for everyday wear and post-surgery comfort.

    Too small

    I’ve had to take off 2 stars as they run very small. I’m normally a medium but ordered a large. They’re still too small and the seams land on my C-section scar. I’d recommend going up 2 sizes.

    Aside from the bad fitting the product is great, it holds the area well and makes me feel more secure. The material is nice and soft making it very comfortable.

    Will definitely order more but in a larger size

    Made a real difference: kept their stretch after washing

    I was unsure whether we really needed it, but it has proved its worth. The waistband stretches over my bump without rolling or digging in. They have kept their shape after repeated washing. It has made everyday life that bit easier.

    Nearly perfect

    Needed something uncomplicated and this has done the job. The cut gives good coverage while still feeling light. The shade is a little different from the website photos, but still lovely.
