Cheap tactics spoil the item!!

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

Yes, I recommend this

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.

Poor quality.

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

Very obvious seams

No, I don't recommend this

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

Probably worst knickers I’ve bought in a decade

No, I don't recommend this

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

Falling down

No, I don't recommend this

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

Bought for a holiday. Thin and flimsy. Creep up and stretched out of shape.

Poor fit

No, I don't recommend this

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

Disappointing fit

Originally posted on marksandspencer.ie

Only ok, poor fit and elasticity. They tend to roll when moving.
