Very comfortable, just the right size for me.
I wondered whether or not to size up based on other reviews. I decided to stick with my usual size, Small (5'1" 115lb) After wearing it, I am very pleased with how it feels. It is tight, but not too tight. It was very tight to get on, but once on it felt perfect. I am happy with my usual size, but I feel like sizing up would be a good option too. I wear mine for yoga, and it is great for that.
Rated 5 out of 5
