Excellent knickers,

Comfortable and fit well, they are very soft and do not cut in on the legs. They also wash well.

Just the best

I have been buying these for years now, they are simply the most comfy, dont know they are there pants i have ever bought. They are very stretchy, smoothing and holding in. If you want a hold in and lift go for a smaller size. I am a size 16, but buy these in size 12, the stretch is very generous and they stay in place, never roll over or down.

Great fit & comfort

A fab purchase in the sale at half price, I have several pairs in opaline & black, but would not have purchased the grape colour at full price. These are really really comfortable knickers if you size down.

Comfortable Underwear For Walking/Running

Originally posted on marksandspencer.com (UK)

These full shape briefs are great to wear under leggings for walking and running. Only been washed a couple of times so far but appear to hold their shape. True to size and came in a mix colour set which was perfect for me.

Super slinky briefs that are comfortable with a looser leg finish. You could almost think of sizing down if you like a more fitted finish. Rich burgandy colour and a full brief that looks classy and modern.

Good but different to before

Originally posted on marksandspencer.com (UK)

Always loved these flexifit pants but these definitely seem a bit looser/bigger than before. Still comfy but too late to exchange as I immediately unpackaged

Good quality, comfortable around the legs and stomach. I like these as they feel soft and don't show through your trousers

Delightful to wear!

So comfy. They may be big berthas but they fit like a glove & really move with you. Trim gives a nice shape, dare I say sexy big pants you can lounge in. The dream! Material is luxurious.

Really great shape

These are a great fit. I usually buy shorts, but actually found these to be a much better ‘short’ shape, and they have a great shape to them.
