A lot more comfortable than I expected. You can easily wear it all day. It doesnt get in the way of breastfeeding at all. Gets serious results, too!

Six weeks postpartum update: I still love this system, but its a little big on me now. I tighten it as much as possible and its still not as tight as Id like for optimal support. If it were any looser, I would say its too big to work properly. Not for you if you're smaller than me - For reference, Im 53, and I was 113lbs pre-pregnancy, 130lbs currently.
