They say three makes a trend. And while Katy Perry, in a sea foam green Gucci 2013 resort wear gown, may have kicked keyhole dresses into a whole new sphere of consciousness on the red carpet at the 55th Annual GRAMMY Awards growing celebrity and designer embrace of the style doesn’t stop there.

The style is poised to make a comeback and variations rolled down the runway during New York Fashion Week from designers like Rachel Zoe (below), Carolina Herrera and Diane Von Fursterburg.

The trifecta who’ve officially made this trend a threesome include Julianne Hough at the Tommy Hilfiger New West Coast Flagship Opening, in a navy Tommy Hilfiger design, on February 13 and Ashley Benson at the Spring Breakers premiere in Paris, wearing a black floor length gown by Amit GT with ample keyhole cleavage on display, on February 18.
