There's no better time to appreciate standout red carpet gowns than during Fashion Week. The Grammys fell right in the midst of NYFW last year, which was the perfect time to digest daring trends and bold silhouettes. The Grammys is the perfect ceremony for celebrities to test the limits. Before singers like Katy Perry, Rihanna, and Lady Gaga changed into their performance costumes, we rounded up their arrival outfits. And, frankly, they might have been just as buzzy. Ahead, see what everyone wore, then check out their stunning beauty looks, and get ready for an exciting Sunday night that's up to par.
