It was all about the peekaboo effect at the 2103 Met Gala.
Thigh-high slits aren't the only way to show a hint of skin on the red carpet. Cutout dresses allows stars to bare their bods without exposing too much of their curves.
And last night nearly everyone in Hollywood took advantage of the style. Elegant LBDs with strategically placed side and belly cutouts reigned supreme on Carey Mulligan and Alexa Chung. While others celebs such as Miranda Kerr, Dakota Fanning and Emma Watson went for sexy dresses so similar you'd have to do a double take to be sure they weren't the same thing.
With all the different gowns and cutouts one fact remains true: The ladies of Hollywood all have fab abs.
