Cheap tactics spoil the item!!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The knickers are fine but I seriously object to having the size and wash instructions stamped onto the item-it is even black ink on white fabric-very cheap tactics and I will not buy again.

Suuuuper comfy

I bought these in black and nude, and I have no regrets. I find the high leg very comfortable, esp as I have quite wide hips. The modal is super soft, stretchy and breathable. I find they wash well, and have little VPL with clothing. These are my new go to. I basically ditched the old ones and have stocked entirely with flexfit knickers and thongs - no regrets.

The material is so thin and does not keep its shape. Such poor quality.

These have really bumpy seams that can be seen even through jeans.

Probably worst knickers I’ve bought in a decade

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Very abbreviated, inadequate elasticity, and knicker liners won’t stick to the gusset. Awful.

Had bought these before and they are a different shape now and no elasticity. Really disappointing…

Falling down

Originally posted on marksandspencer.com (UK)

Dreadful. Had the embarrassing experience of wearing a new pair under a dress and going for a walk. Within minutes I had them falling down around me. Had to go into a store to buy replacement knickers.

Not great

Lovely soft fabric however they don’t stay in position across tummy. Also the gusset is very narrow and can’t accommodate a panty liner
