I bought this at a local store for 9.99 because i really want to see if it worked and it really does!! I wore a racerback tank top and strap perfect helped hide the straps perfectly.  It is fitted and for some I could see it being too tight, but it doesnt bother me at all and you can always mess with it til its comfortable.  I don't feel it on my back either. And yes it does make your chest appear a little more fuller!
