The complete inner breast area, top to bottom. Different from cleavage in that the upper center boob is not exposed, but the entire inner boob area is. Boobs also are not pressed together. Paragon would be Katy Perry in chartreuse dress at the 2013 Grammys. Several other examples of women presenting awards from 2012 - 2017 at most non-country music awards shows exist as well.
Wardrobe choices are so limited for flat-chested women who have to present awards nowadays. They have no inner boob.

Dude 2: "You mean cleavage?"
Dude 1: "whatever."
