All the time you've been putting in at the gym is about to pay off — because in these dresses, your abs have nowhere to hide. With bold, midriff-baring cutouts, they might just be the easiest way to stay cool in the sweltering heat, but that's not the only plus. Since a slit at the sternum or right at your middle is a more unexpected way to show skin, this trend is all about bringing sexy back with one big twist. Don't just take our word for it — flip through the celebrity inspiration, then pick up one (or two!) of your own  for your next hot Summer night out.
