Big!

No, I don't recommend this

I am definitely a size 14 and a high waisted shaped. These were big. The gusset was small. Generally felt uncomfortable- I may try a size down as the fabric and style is good for my clothing.

Gusset too saggy but great material

No, I don't recommend this

These smooth thongs go great under leggings and have no vpl but after an hour of wear they seem to go saggy and I reckon they could pull up as high as my ribs! I should have listened to other reviews as basically the front triangle is too narrow for any middle aged coverage and gusset too long/too stretchy which means they ride much higher than high waisted trousers. I am always a size 12 and bought these in a 12. I like the smoothness of the fabric and great for tummy coverage but they are just too loose around the gusset.

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.

Very comfortable and the cut is lovely, fits well. I am going to order some more in the other colours now too as they are so comfortable - very soft fabric.

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.

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
