Modal full briefs

No, I don't recommend this

These briefs are very thin, offer no support at all. A total waste of money

Super comfy

Yes, I recommend this

Really lovely, buttery soft and stretchy. I use them for that time of the month where I need to use pads of varying sizes, they are absolutely perfect. The high cut on the leg really adds to the comfort without taking away any integral part of the garment. I have only washed them a couple times, but I have also tumbled them and there are no visible signs of wear/tear/pilling. Hoping they keep shape and vondition for a while, if they do I will order a couple lore multipacks.

Theres not enough material across the behind and the material dissapears when you move and its not a great look if your trying to pluck it back out!

Disappointed

No, I don't recommend this

I have been buying these knickers for years now and so as normal just ordered 6 pairs In total 2 packs of 3 pairs … the fit is definitely not the same and I’m really disappointed they have defo come up smaller and feel like a totally different product … sort your sizing out M&S I don’t know what’s going on but you seem to be working on smaller sizing and it’s not good for your regular customer

Easy to wear Flexifit knickers

Yes, I recommend this

Needed to replace my knickers with new. Find these so easy to wear , you don’t even know you have them on!! I would buy them again. They are so light & the cost is good so you can buy several pairs! Also they don’t take much space in you draw or suitcase.

They are so comfortable

I love these. They are very different from what I have been wearing for years - the material is lighter and softer - there are no cotton lace trims around the legs and the waist which get scratchy over time and no annoying seams going down the back.

Lovely soft knickers that offer support and coverage so you feel neatly tucked in! True to size too. Great shape on the body - good coverage but not old fashioned in any way !!

For some Reason I had to size up with these briefs from my last set. Not that size matters over comfort! Just odd sizing.

These knickers are so soft and comfortable I had my daughter send them to me in USA. They’re worth every penny of the extra postage on top too.
