When it comes to picking out a sexy gown, Irina Shayk and Beyoncé appear to have the same taste. Irina was the first to don her black Roberto Cavalli cutout dress at the All Is Lost premiere at the Cannes Film Festival back in May. Then, last night, Beyoncé chose the same plunging gown in white for the 10th anniversary party of husband, Jay Z's 40/40 club in NYC. Irina's gown was definitely on the more revealing side, while Beyoncé's look blended sexy with ethereal. Both ladies clearly let their gown do all the talking — and really, that's all they needed. So take a good look at these two in their Roberto Cavalli gowns, then tell us, which bombshell's take do you prefer?
