Expectant mothers need comfortable and supportive undergarments that can accommodate their growing bellies. Cotton maternity knickers are a great option for women looking for breathable, soft, and stretchy underwear that provides ample coverage and support during pregnancy. These knickers are designed to fit snugly around the waist and hips without digging into the skin, and their high-rise waistband helps to stabilise the belly and provide a comfortable fit.

Frequently Asked Questions (FAQs)

1. Can you buy maternity knickers?

Maternity underwear is designed to fit your growing belly throughout pregnancy and so will stay in place a lot better than your regular briefs - it's recommended you buy maternity styles to save your non-preggo pairs from stretching out, even if they do still fit.

2. Do you need bigger knickers when pregnant?

Most women know their bodies and will have a good idea of how much weight they are gaining. I recommend my customers and pregnant friends purchase a couple of pairs of underpants 1 size bigger at the beginning of their pregnancy and then a few more pairs at about 5-6 months, 1 to 2 sizes bigger.

3. What are the best knickers to wear after birth?

Best Postpartum Underwear. Most Versatile Postpartum Underwear : Motherhood Maternity Foldover Brief Panties.Best Adjustable Postpartum Underwear : Leonisa Firm Compression Postpartum Panty with Adjustable Belly Wrap.Best Full Coverage Postpartum Underwear : Wirapa Breathable High Waist Cotton Underwear.
