Love these!

Yes, I recommend this

The material is really soft which makes them very comfortable. They also pull up right over the bump so dont ride down, and keep you warm in the winter months!

Very uncomfortable! only wore them once. The last thing you need when pregnant is to add to the uncomfort

Brilliant - but why only online?

It's very unfortunate that these aren't stocked in stores, so you have to purchase them blind while at such a sensitive stage of life & completely lost as to what fits your growing body. That said, they are super comfortable and stretchy — I sized up, so they're flush to my body but not tight at all, and they'll fit me all through the rest of my pregnancy. They're not quite "seamless", but the VPL isn't that noticeable.

Material is not breathable at all and there is no pantyliner in them. Had to return them.

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!!
