Holes in back of underwear following first wear

No, I don't recommend this

Holes in back of underwear following first wear, pretty bad quality if they don’t last that long.

Comfy but runs a bit big

Yes, I recommend this

I think as this is a stretchy fabric if you are in between sizes, size down!!

Comfortable but more supportive would be nice

Nice soft comfortable material. A firmer more supportive waste would be better to hold you especially with them being high wasted.

Disappointing

Nice high waist that didn’t roll down but fabric thin and the front too narrow to be comfortable. I will not be recommending or buying again.

Great feel and fit.

The knickers were bought for valentines as a gift for my wife. She says they feel great and fit perfectly which is always a bonus. I can vouch for the look and the modal feels great.

Comfortable Thongs

Yes, I recommend this

Great for 'no panty line' Had to go for the size 6 as too big otherwise. Im usually an 8 in M & S.

I’m an M&S size 10 in jeans and pants but always buy underwear 2 sizes bigger for comfort. Love these, I’m usually not a thong wearer but I really like these, so soft and comfortable

Wouldn’t buy again

No, I don't recommend this

Don’t think I would buy these again. I like pants to cover my tummy area but I think these come half way up my ribs. I also think they are too narrow at the front.

So comfortable and a flattering fit.

Yes, I recommend this

Such a comfortable fit, love the soft material, high waisted and wide at the top of the thong. I straight away ordered more and also different colours.

Goes a bit saggy

No, I don't recommend this

Goes a bit saggy around the crutch after a few hours of wear. At first they feel great but then they loosen.

Very comfortable

Yes, I recommend this

These are a really great fit for ladies who wish to where a thong but want a little more coverage! Sizing is good but I always size up for a more comfortable fit. The down side to these is that they are functional not particularly pretty? No lace or detailing… And M&S why is it that there are sooo many high waisted jeans/trousers etc but so few everyday high waisted thongs & lack of colour range? M&S come on… must do better! Thank goodness you finally brought out white too when a vast majority of your bras are white!? In short they are great but need a little more choice…

Amazing thongs

Yes, I recommend this

Love these thongs, they are so comfortable and they are high at the waist, great when wearing a dress you can't see any lines. Going to buy some more of these.

Poor quality!

No, I don't recommend this

Quality isn’t great. Don’t fit very well and the material is cheap. Too expensive for what they are.
