I ordered one size down and the overall fit is good, but they are super super long. They are not ankle length at all. I'm on the fence about returning them or not. Too expensive for me to wear as pajamas.
These are my all time favorite leggings. I own 3 pair, and am ordering a 4th. They are thin but they are actually very durable. I can't tell the difference between my new ones and ones I've had for years. I love the smaller waistband, it's functional but comfortable. The lightweight material makes them easily wearable in warmer weather. I've had no issues with them not staying in place, no snags or pilling, and move around quite a bit at my job. They are pricey for a pair of leggings but they have more than earned their keep in my closet. I live in them..I wear them almost daily, to work, around the house. I've even slept in them. I've purchased other brands and I always come back to these, so I've just stopped wasting my money on others.
