I followed the size guide and ordered XS and it fits perfectly. I got the same one in colour black and for some reason, black colour is a bit tighter (but still fits well). 

I bought 3 unwanted, returned, bad sizing inspire leggings along with these ones. This was the only leggings i kept. Fabulous fit. Tight high waistband & colour & material is lush. Just like all their previous leggings before they decided to change the sizing & materials for the inspire range. Love these leggings. Going to buy the full colour set. I bought my usual size XS fits like a glove. Unlike the inspire range. Had to size up to S & still did not fit. Shame.

Great pair of leggings! Love the high waist design, they’re squat proof, comfortable and hold you in all the right places. A bit on the long side but I’m short so I’m used to it. 

Love these! They fit like a glove! Fantastic colour found a matching hoodie to go with it. They will look fantastic all year round perfect to wear to the gym in the winter or the summer. 

I am 5'4, wear size 12 River Island jeans and size M in Nike dry fit leggings. Bought these in size M. AMAZING. they are high-waisted, squat proof and they really hold you together. Delighted with them. A little on the long side but not a bother to roll them up once or twice. Will definitely be buying more shortly and my mum wants a pair or two also.
