Poor quality

No, I don't recommend this

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.

Haven't disappointed!

Yes, I recommend this

This is my third pack of Body bikini briefs size 12. Following the second pack being cut slightly smaller , with a slightly narrower gusset, I was uncertain re purchasing again. However, I have been pleasantly surprised that no further 'savings' have been made in the fabric/design and they are well made and comfortable. They always wash well and are durable...although my original pack are starting to look a bit shabby now - hence the new purchase.

Good Quality Underwear.

Yes, I recommend this

Bought this set of underwear specifically for every day usage. They are lovely quality & have a nice feel to the material. They are perfect for what I want them for and a good price for what you get. I like that they are all a different colour and also like the little detail on the band. They are a perfect fit, too. I would buy these again and I am happy to recommend.
