I have recently bought a gk bra, they are very good i just reccomend getting the same size that you would order your leo as because the fit will be coresponding. Another good place to buy bras is target.
i have GK ones and they rock. my mom bought me one from victorias secret and it is really good but it was expensive. anything that isnt padded and fits works just fine, you need not fret about getting the right one!
