At first I thought the size was great.  With in an hour it was way too loose and I had not worked out yet. The straps are poor material and give too much. Which can not be corrected because of the design. The only recourse is to tug downward and that leaves you with trying to then readjust yourself into the bra. At the end you are all up at the to of the bra.  Not sure how or why the rating are so high. Just a waste of my money and space.
