Ladies, if you like the look of the waist-revealing dresses that have been spotted on the red carpet recently, then make sure to carve out extra time for crunches at the gym.

In past seasons, celebs couldn't get enough of tent-like trapeze dresses, but those comfy styles are no longer en vogue, and in their place has emerged their polar opposite: skin-tight dresses with side-panel cutouts, as seen on stars Christina Ricci, Kim Kardashian (in a Wayne design), and singer Ciara.
