The best maternity knickers

Yes, I recommend this

These are the only maternity knickers that I have found to fit properly and comfortably, and don’t compress or irritate my bump. I keep coming back to buy more as I really rate them.

Good quality, true to size

Yes, I recommend this

Comfy and true to size. Would prefer a cotton lining rather than it all being one material, however, the pants are breathable and comfy.

Love these!!!

These are honestly the BEST choice of pregnancy knickers. I wasted time buying some from other companies and ended up returning them three times. I should have come straight to M&S as they are true to size and actually comfortable. Love these!!

Too itchy knicks. fir last weeks in pregnancy

No, I don't recommend this

Material too itchy, uncomfortable and chaffs at upper legs, so daughter couldn’t wear. Maybe do in cotton with some stretch at tummy for comfort

Super comfy

Yes, I recommend this

Got these at 7 months pregnant and they are a dream, so comfy, stretchy and will be really good for post partum too. They could do with a cotton insert like others have said, but otherwise they are great.
