Where: The 2015 Grammy Awards at the Staples Center in Los Angeles.
When: Sunday, February 8th
What: A pink Giambattista Valli Spring 2015 couture dress and Chopard jewels.
Why: Rihanna's massive pink gown and sweet hair and makeup—not to mention all the memes this look inspired—was all anyone could talk about after the Grammy Awards. This one is going to be tough to top in 2016.
