After everyone turned up at the Met Gala last night, Rihanna hosted an after party in a dress that showed off her assets, or at least part of them. Her shimmering gold dress was cut so that a good portion of buttcrack was exposed to the spring time air, begging the question, "Is topbutt the new underboob?" The dress also featured a thin gold chain that stretched across her coccyx. 

The intentional "plumber" move came on a night in which the fashion focus was on the men of the Met Gala, who either adhered to or broke the "white tie and decorations" dress code.
