I work in a cold office at the computer all day long, and suffer with a bit of tendonitis. These sleeves are one size, and if you're skinny and suffer with the cold the nice surprise was the cute ruching that wads up over your wrists. I was not expecting that, but the shadow stripe knit actually makes it look very pretty - my work colleagues asked when they saw my knitwear peeking out from under my blazer!
I wear this straight from the office to gymnastics, and the sleeves just look so cute and hold up for stretching and dancing around.
