While most swimsuit shoots and magazine covers stick to normal cleavage for women, these underboob innovations dare to take exposure in a different direction. These underboob finds are proof that even something as minute as cleavage can change over time.

There are many ways to produce a successful underboob photo shoot. One way is to fit the models into low-cut tank tops that reveal just the bottom. Another method is to just forget the clothing altogether and have the model simply use her arm to produce the underboob effect. Even Jennifer Lopez showed the bottom of her breasts when she posed as a naughty boxer for 'V Magazine 76.' One thing is for sure, this isn't the last of the revolutionary cleavage movement.
