BF Heidi Bra (Japan). If you are ready to experience an amazing full figure bra, then this is it. Like nothing you've most probably experienced before, this bra comfortably but firmly cradles and positions the breasts in the maximum comfort position. Before it does that, and due to its wide and firmly stretch side panels, this bra collects all back, side and underarm fatty tissue and moves it to the cup. The innovative design also features a stretch-net fabric along the wire contour to allow maximum breathability and comfort. Its truly one of a kind design and bra, as are most Belle Forme bras.
