Demi bras, also known as balconette bras, are a half-cup bra style with
wide-set straps and a horizontal bust line. Often seamed or boned, they
promote cleavage and a frame-like effect. These offer less support but
enable low-cut garments to be worn without the bra being seen. Demi bras
may be designed to provide lift as do push-up bras.
In other words, it's an old style bra that pushes your boobs up and closer together.
