I had hoped this was something I could wear to help with my shoulder alignment and upper back pain.  Maybe it would, if it fit right and didn't cause even more pain. The straps are too short for me, so no matter how snug i set the under band, the back hikes up and gaps in the middle and the part that is supposed to fit UNDER the bust cuts painfully (and weird-looking!)across them.  I tried switching to the clear straps which are a bit longer, but the hardware on them hurt my skin where you have two straps (and thus twice the hardware)on each side instead of one.  In theory, this should work and it appears to be well-made... but unfortunately I'm going to have to figure out how to make some longer, more comfortable straps for it if it's to be used at all.
