Rihanna and Beyonce seem to be having a crazy costume arms race. Beyonce has recently dressed like a pirate and a transformer and last night at the AMAs she decided to try the fishnet stockings look that Rihanna rocked last week while Rihanna answered with crazy tight leather and spikes. Keep 'em coming ladies!

What do you think of Beyonce at the AMAs? Who rocked the fishnets better, Rihanna or Beyonce? Leave a comment below!
