Taylor Swift had us trained: red or gold, sparkles or sequins, evening gown or flippy party dress. Those were the red carpet options.

But since that memorable moment at the 2013 People's Choice Awards , when Swift wowed everyone (including, we bet, her ex-boyfriend Harry Styles) in a slinky white dress with a plunging neckline , Swift seems to have entered a sexier, bustier phase. At the 40 Principales Awards in Madrid on Thursday night, the songstress debuted another plunging white Kaufmanfranco dress, this time with what can only be described as rectangular cleavage.

Which, unfortunately, is not the sexiest cleavage shape in the book. But hey, this is still a step in the right direction (so to speak). Does this finally mean that T-Swift and her sparkly, sweet dresses are never ever getting back together? Fingers crossed.
