A lot of girls fantasize about getting married (maybe even to Harry Styles) and wearing a gorgeous white wedding dress. Taylor Swift , really, is no different: She just has a much, much bigger platform than most hopeful brides-to-be.

Thursday at the Brit Awards in London, the 23-year-old singer performed "I Knew You Were Trouble" wearing a prim, lacy, kinda-poofy dress that looked an awful lot like a wedding gown.

Taylor very delicately pranced around the stage, looking very proper and ready to say "I do" in her pristine white dress. Ex-boyfriend Harry Styles, who performed with One Direction earlier in the night, watched on from the audience.

Then—in a Sandra Dee moment—the country-pop star's dancers ripped off her conservative dress. Beneath that, Tay wore a low-cut lace top, leather hot pants and knee-high black boots. She also dramatically took down her hair, walked hard and danced provocatively on the now fiery stage.

It was...something we will never, ever, ever forget.
