Great tank. I think I'll be wearing it everyday! Super easy to nurse in, I don't even use a cover anymore. I'm 5'3 and 126#, ordered an xs. It really tight, but that's how I wanted it. My only complaint would be that it rides up so I'm constantly pulling it down. And just an FYI, it looks funny if you wear it alone, because of the spandex middle. But great for layering and not too hot.
