The Tally bra is made of the softest 60% Nylon 40% spandex, 4 way stretch, breathable fabric on the market. This fabric allows us to have the support we need but also allows us the comfort we demand. The Tally has dye to match elastic criss cross adjustable straps. This allows us to wear it with a racerback or a regular tank. This also allows all sizes to make it work for them. Versatility is the name of the game and its comfort takes the cake!
