Excellent fit. Being plus sized it can be difficult to find activewear that fits perfectly and doesn’t roll down during exercise. These leggings are flattering! I’m usually a UK20 and I ordered the 2XL, perfect fit, plenty of room to move about in. I would say that if you’re on the tall side, these may come up a little short. I am 5ft 1, the length is perfect for me - which is unusual in my experience!
