Been looking for some over the bump knickers and these ticked all the boxes. Only comment would be its tan white and navy. I was hoping for black

Not cotton and more like a bikini bottom

No, I don't recommend this

Nothing wrong with product but they aren’t made from cotton as I think underwear should be. There is no gusset so it is like a one piece bikini bottom. Stretchy and comfortable over bump.

Average

Soft material, fits over bump well and comfortable. Material a little thin and seams could be softer and dig in ever so slightly. Not worth the money overall, but not many on the market. Overall fine.

Very comfortable

Yes, I recommend this

Bought these for my daughter who is in her 2nd trimester of pregnancy as I overheard her saying that her panties were uncomfortable. She said they were the most comfortable briefs she now owns as fit nicely over her growing bump. Loved them so much that she ordered two more packets for herself!

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!

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.
