Rihanna arrived at this year’s Grammy ceremonies wearing enough pink tulle to outfit both Katy Perry and Taylor Swift’s backup dancers should the need have arisen. Naturally, her enormous, empire-waisted Giambattista Valli dress prompted swift reaction from the Internet. By the end of the night, Rihanna resembled everything from a Dominican cake topper to a shower pouf to a bottle of Pepto-Bismol.

There were a lot of quinceañera jokes.

Even another fashion label, Opening Ceremony, got in on the action.
