Wearing an eye-catching gown from the Giambattista Valli Spring 2015 Couture collection, Rihanna made waves by appearing on both the best and worst-dressed lists.

She was joined by Miley Cyrus, Nicki Minaj, Lady Gaga, Iggy Azalea, Katy Perry, Beyonce Knowles, Taylor Swift, Madonna, and Ariana Grande at the 2015 Grammy Awards at the Staples Center on Sunday in Los Angeles.

The 26-year-old wore a strapless cupcake-pink dress with such dramatic volume that even Rihanna found it challenging to pull off.

She seemed to have a lot of fun on the red carpet and accessorized with Chopard jewelry.

Do you think Rihanna was one of the best or worst dressed at the 2015 Grammy Awards?
