Too small, get one size bigger

I have been using these for the last few years, always size 12. I bought some at the outlet at Ashford about a month ago, again size 12, these feel a bit tight. Compared with the others the new ones are smaller, very dissapointed with this as I have washed them. The new are uncomfortable.

Comfortable and nice soft material. Only had them a couple of weeks before some stray threads came away from the seams though

Lovely fabric

Yes, I recommend this

These fit perfectly and the fabric feels lovely on. Love the new pinky/purply shade. A full knicker but somehow doesn’t look too frumpy, will be back for more.

Accidental joy

Yes, I recommend this

Ok, so honestly, I bought these by mistake. I didn’t realise I’d purchased the full briefs. Whoops! I wasn’t sure if I could return them, so just took the hit and wore them. As it turns out, they’re amazing. Soooo comfy and everything I could hope for in pants. I’ve been converted, and plan to buy more! They are light and comfy, don’t dig in or roll down. What more could you want!

Quality and fit reduced

No, I don't recommend this

These were my go-to knickers. However, the fabric has changed and reduced in quality. Most annoyingly, the flex fit binding is significantly different in shape and quality - less than half as wide and no where near as silky. These don’t give the comfortable coverage around the leg and bum that they did - they ride up now. Who is designing M&S underwear now? Gussets too narrow and fit uncomfortable. Most designs won’t even support a regular pantyliner! Look fine when you’re standing still, but move about too much and they become a thong. Utter disappointment

These are so comfortable to wear & the three pack is good value for money especially if you can buy them with a discount. They are a good fit & wash & dry well.
