What underwear does bra use to correct the chest contour? The front button, or the gathering effect, or something else?
You can wear adjustable bras, but generally adjustable bras are expensive and have no front row, but the effect is quite good. I know that several brands are ok, and they all take the beauty salon route. Messani, Mark Baodi and Tregoni are all good. I wear Baodi and Messani myself, and I feel ok.
