Did you catch the Grammy's? There were a ton of performances, and with each performance there was inevitably...a wardrobe change! We've picked a few of our favorite performances and lined up each singers red carpet look next to their stage look.
Katy Perry had 4 outfit changes over the course of the night. Her first was Valentino, then a witch/goth-like costume for her "Dark Horse" performance. Later in the evening she changed into a maroon Valentino Couture dress and ended the night in an icy-blue prismatic halter dress.
Beyonce wore Michael Costello on the red carpet and La Perla for her performance with hubby, Jay-Z.

Kacey Musgraves wore a sparkly Armani Prive gown and then changed into an a-line, heavily bedazzled dress for her performance of "Follow Your Arrow."
Taylor Swift wore a golden metallic Gucci dress on the red carpet and changed into an ethereal Alberta Feretti gown for her performance of "All Too Well."
Sarah Bareilles wore a Blumarine embellished dress for the red carpet and then changed into a black, brocaded sequined dress for her performance with Carole King.
MARGOT ROBBIE - The Wolf of Wallstreet star looked breath-taking in this champagne gown by Gucci with emerald accents.
OLIVIA WILDE - Who says being pregnant has to mean boring fashion choices? The Rush actress was absolutely glowing in this sparkly green Gucci dress.
KATE MARA - The House of Cards star looked fabulous in this futuristic, plunging neckline, grey J. Mendel gown.
ZOOEY DESCHANEL - Finally, the New Girl actress found a gown that matches her feminine vintage style, while still looking fresh and couture. We love her in this Oscar de la Renta dress!
ZOE SALDANA is normally so put together, but she missed the mark with this Prabal Gurang dress.
RASHINDA JONES - We like that she took a fashion risk, but unfortunately, this one didn't pan out. We just don't understand the gaudy palm trees on her Fausto Puglisi gown.
AUBREY PLAZA - In Oscar de la Renta, another Parks and Recreation, actress who fell flat.
HAYDEN PANETTIERE - The jury is still out on whether or not Tom Ford's team actually selected this dress especially for the Nashville star to wear. So far, they have only confirmed that they dressed Naomi Watts for the evening. So did she buy this dress off the rack? If so, we just can't understand why.
TINA FEY - First of all, let us just say that we love Tina Fey and the dresses she actually wore to host in. Unfortunately, the dress she chose for the red carpet by Carolina Herrera was a total miss. I mean, are those flowers or flamingos? Either way, not a flattering look.
We can't decide if we love or hate the Prabal Gurang color-block dress that SANDRA BULLOCK wore. She looked beautiful, and it fit well, but the bold colors are a bit odd. What do you guys think?
