So thin they are almost see through, don't bother, shocking quality for more money.

Far too small

I bought a pack of these in size 8, which is my usual size for M&S and they were ridiculously small. I couldn’t wear them and as there is no chance of a refund on underwear they had to go straight in the bin. What a waste. Make sure you buy at least one size up!

Decent value for the quality and comfort

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Good value as usual. I've bought these for years. Decades, in fact. These cotton lycra ones are superior in seam/stitch quality and comfort (ie they don't roll down at the hip) compared to the other fabric (llyocell?) bikinis.

Ordered in error

Couldn’t find the midi version I like so ordered these. They aren’t as comfortable and finally by using code found the ones I wanted which are now called shorts!

True to size. Washes well. However, the material has become a lot thinner and more see-through lately compared to what it was before. A little disappointing.

My goto for pants. I don’t know if tgeir sizing has changed, but these size 6 seem looser than old size 8’s. Might just be because they are new?!? Love them, except silly bow

Classic cotton knickers with a little stretch to help the fit. Daughter and I both wear this style and hope you don’t stop making it in place of something more fashionable! They wash well and are comfortable.
