Say hello to the keyhole cleavage.

Focusing on the tummy, it highlights the space between your underboob to just above your belly button. The more daring styles crank it up a notch, also exposing the inbetween-bits of your boobs rather than the top.
Country star Faith Hill (in red) kept it small, Kris Jenner (in black) added a sheer layer of fabric while singers Demi Lovato and Carrie Underwood took the cut up high. (Post continues after gallery.)
Another fan of the keyhole? Jennifer Lopez.
More 'peek-a-bo' than the 'in your face' nature of some of the various dramatic slashed necklines we've been seeing of late, it can be as subtle or as, erm, not subtle as you like.
This versatility means it's not restricted to any age or boob size either (that is of course if you even care about style 'rules' to begin with).
Having been around for a while, the style isn't just limited to dresses, proving popular in everything from everyday tops to swim wear.
Here are some other (more wearable) keyhole pieces we'll be adding to our wardrobe, no red carpet event required.
