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

Yes, I recommend this

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.

Great quality

Yes, I recommend this

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

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

Flexifit knickers

Yes, I recommend this

Previously ordered Flexifit knickers but having lost weight needed smaller ones. I was delighted to find them in different colours and ordered two sets of three. They are so soft & comfortable to wear and colours are lovely. They wash very well either in washing machine or by hand. Highly recommend them.
