A balconet (or balconette) is an architectural term to describe a false balcony, or railing at the outer plane of a window-opening reaching to the floor, and having, when the window is open, the appearance of a balcony. They are common in France, Spain, and Italy. They are often referred to as Juliet balconies after the scene from Shakespeare's play Romeo and Juliet.
The term has also been applied to a style of brassiere featuring low-cut cups and wide set straps that give the appearance of a square neckline. The name "balconette" came from men in the balcony of a theatre looking down upon women. A balconette bra could not be seen from above.
