About the balconette cut:

The balconette bra creates a lifted décolleté: the neckline runs horizontally, the center gore is high, and the straps sit wide apart. The cup cups the breast from below, lifts it, and brings it toward the center – for a seductive neckline with solid support. Popular not only for bras but also for corsets and evening wear.
