I don't recommend these, they slide down. Very annoying when wearing dress

Perfect and as expected. Very comfy, great fabric and good value- always get my underwear from M&S as they last and wash well.

Fabulous fit.

Husband bought me a pack of 3 for Christmas a few years ago and they fit and feel lovely. I needed more so bought a pack of 10 ordinary cotton pants but they have a seam on the edge of the legs which just seem to cut in and feel tight so I treated myself to a set of 3 black and a set of 3 multicoloured of these. They’re lovely, you don’t even realise you’re wearing them. Would recommend.

The material is very poor, virtually see through once on. Disappointed as previously purchased and expected same quality. Won’t be making that mistake again.

Comfiest Underwear

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These are supportive, stretchy and super soft I threw out all my other underwear and bought in all the other colours. I usually order a size larger than I am for comfort but these I sized down for a little extra tummy support after reading other reviews and even after giving birth and they fit prefectly. Love these

I’ve been buying these pants now for a few years. The quality is excellent and they wash lovely. The nude colours are a must, they go with everything and definitely no Vpl. The fabric is lovely and soft.

These knickers are lovely, I love the fabric feels like you’ve got nothing on. However the sizing is really perculiar and I would size down.

Not a well fitting as they used to be, more like brazilians than full briefs
