Panties our underwear

No, I don't recommend this

Panties or underwear , I had high hopes for this 5 pack, but unfortunately they didn’t meet my expectations. The fabric feels loose even I got the right size, and uncomfortable against the skin. I prefer the other one I got few months ago. Much better.

Nice as they are cotton but size up

Originally posted on marksandspencer.com (UK)

Nice but don't cover too much skin, are quite skimpy and maybe size up. Could cover a bit more of the front!

Sized up and glad I did. Bring cotton, they shrunk on the first wash. Otherwise, does the job!

Nice material, sizing is on the small side.

Originally posted on marksandspencer.com (UK)

Nice, natural material - which is always preferable over synthetic materials - however I ordered a size 14 (I'm a 12/14) and these are definitely on the smaller side I find!

Quality is average

These are fine, but quite thin material, borderline see through. I wouldn’t be buying again.

Good Quality

Originally posted on marksandspencer.com (UK)

This is only a recent purchase so I cannot give a proper review but so far they fit well and feel good quality (especially because they are made out of cotton). Definitely tempted to purchase them again down the line. I prefer these over the miceofibre thongs. I tend to find the microfibre thongs loosen over the day but these do not.

Nice quality cotton but gusset is too narrow please make the gusset wider, I'm a slim person so would not recommend for larger ladies.
