This binder is easily the most comfortable and best-looking that I have ever owned.
I'm a big person - I fit a 2X, and while my breasts are proportionate to the rest of me, there's still a lot of mass to flatten. My expectations were totally blown away by this tank. It was completely skintight - none of that extra fabric at the armpits that you have to wear a loose overshirt to hide. Wearing it makes my chest look as flat as any breastless fat person. (That is, it's not *gone,* because all fat people have some squish up top. Looks like pecs.) It's very comfortable wearing around - it's elastic everywhere, there's no solid binding panel, it really is just a stretchy tank top. Furthermore, it lives up to its back support advertising as well - mine was killing me, and this piece helped wonders. And finally, if you're someone who likes pressure - think weighted blankets - this tank top is lovely on that front. I'm autistic, and I find it very grounding. The compression is more evenly distributed than any other binder I've ever owned, which increases my satisfaction.
My *sole* discontent with it, was that it is longer than my torso has space for, because I am short - I have to fold up the bottom maybe four inches. It covers my boxers completely if I pull it all the way down. I don't actually find this an issue at all, and it won't even slightly hinder my purchasing it again in the future. I like how it's long enough to compress all the way down my butt, instead of ending at the hips or something. I point this out simply to highlight just how happy I am with it.
