Not bad but...

Yes, I recommend this

Not bad but need an extra layer of protection at night or heavy days. The black pairs were very comfortable but the leopard print ones were a different cut and dug into my legs. Saved me on light/ medium days and washed well no shrinking.

Fit well

Yes, I recommend this

Like these as fit well. Work as expected, pricey if full price but good value in sale and would have bought another set if had still been available.

Too too high cut

No, I don't recommend this

Too small in my honest opinion for a period pant. Would benefit from more depth, less high cut please

Okay- good value for money

No, I don't recommend this

Okay but the gusset feels quite wide (making it dig into my inner thighs) and the sizing seems a little off. They seem to want to fall down despite an 8 being my right size in all other items.

Sizing has changed - less comfortable

No, I don't recommend this

This is the 3rd set of m&s period pants I've bought and unfortunately they seem to have changed the sizing or elastic. Uncomfortable around the legs now Shame because until now I've really rated the period range.

Lovely quality, poor fit

No, I don't recommend this

The product itself is made very well. However these came up so small and I was unable to use them. The leg holes are tiny and cut into my legs, I think the cut of the product needs to be improved. I recommend sizing up by 1 or even 2 sizes.

Definitely not 'Heavy Absorbency'!

No, I don't recommend this

Required a couple of pads inside the pants, which defeats the object of the pants. They were fine for the lighter days (not great, but fine), but really no good for the heavy days.
