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.

Comfy knicks!

Good style and colour. Very comfortable. Good to fiind knickers without visible elastic at waist.

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

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

Not the same as the past ones

Really disappointed with these. They used to have a modesty strip at the front and to save money they’ve taken it away so now I buy the size up (14). They are way too big and I should have saved my money

Very poor quality,

No, I don't recommend this

Very dissapointed, if I could have returned I would have. After 30 years of buying knickers from M&S I am going to start looking around. These knickers have no hold whatsoever, they are extremely lightweight and just cause annoyance. Tried twice so irritating to wear I will prob just have to bin. Such poor quality/design is wasteful and costly.

Great & not so great

Yes, I recommend this

Great in hot weather, so much better Han cotton modal for keeping you comfortable and dry, bizarely ok with shorts or trousers but hopeless with a skirt or dress as they ride up where they shouldn’t !

Improved quality

Yes, I recommend this

4 pairs out of the 5 pack I ordered last time went in the bin as the stitching unravelled after a couple of wears. Worn 2 pairs from this new pack and they seem ok - up to now!

Don’t stay in place

No, I don't recommend this

The fit is very poor. Without decent elastication around the legs the knickers ride up into places they have no right to go. A waste of money.

Baggy knickers

Knickers lose their shape and get baggy. Not good for me
