Great quality but a bit small.

The pair I tried on were, unfortunately, a bit on the small side but gave the rest to a charity shop, so someone will benefit.

Not quite the same as previous years, I say this as 2 out of the 4 in multiple packet were smaller then the other 2. So 2 were correct size as advertised. I did go into M&S & this was quickly resolved. So I would say normal size fit if all correct.

I’m a size 10 in trousers at M&S and a 14 in underwear hence had to return them. (🤷🏼‍♀️) Happy with the end result and quality of the product. Soft, flexible and no riding.

Very comfortable and a good fit. Pity about the mix of colours - the white ones got thrown out immediately! Don’t have any white clothes as high maintenance!

Poor quality

Originally posted on marksandspencer.com (UK)

I have been buying M&S bikini knickers for many years. I am still the same size 12 but have seen the quality deteriorate over the years. They are now very skimpy especially at the sides and the waistband is very thin. I bought two packs, one of each colour and one pack is better quality than the other as they are manufactured in different countries. They are very cheap and I would rather pay more for better quality.
