It is a very pretty top, I really like the back.  But it is too low cut for actual exercising, I had to keep pulling it up.  I will have to wear it with something underneath that is higher cut.  (I am only a "B" cup and I was getting some major cleavage showing when leaning over for exercises, NOT what I want when working out.)  Also need something underneath it because, even with the shelf bra, that has no small liner cups, it is so THIN that nipples show through if it is cold at the gym.  Could have been a great workout top, now I have to wear something under or over it.
I did like the length.
