Cleavage Window

In anime, when a girl's clothes for some reason has a hole in the middle of the chest that lets show her breasts, the term for that in Japanese is tanima hooru 谷間ホール, literally "cleavage hole." In English, it's usually called "cleavage window," or "boob window."

A single word term for it is "keyhole." Sometimes, it's also called a "peekaboo."
