When I got home today I was able to put cups in the tank, move around in it a little, and compare the fit and look to my Deep V tanks. When I tried it on in the dressing room, the tank seemed to show a liveable amount of cleavage. However, when I tried it on at home today and was able to move around in it a bit more the cleavage went lower and I had to keep yanking the neckline up. I think the weight of my boobs just overwhelmed the construction of the tank. The cup portion is made of light luon and the straps are luxtreme with elastic inside that attach to a racerback portion made of circle mesh. The light luon and circle mesh are both pretty stretchy so if you are very busty, I think this tank won't work for you unless you don't mind showing a lot of cleavage. I thought the support of this tank is on the low end of moderate, similar to the Inner Strength tank.
I compared the Deep Breath to a couple of my Deep Vs and a CRB:

All in all, it's a nice lightweight tank. It definitely shows less cleavage than the Pure Balance tank but more cleavage than the Athletic Deep V tank. It probably shows about as much cleavage as the regular Deep V tank but the materials are stretchier (the regular Deep was made of luon with a power mesh racerback) so I think the tank will tend to creep down if you have any sort of weight in your breasts at all. Be sure to move and bend in the dressing room when trying this on. I think the tank runs on the larger side so you might want to try a size down from your normal tank size.
