Although the styles are slightly different, do you think Rihanna or Katy Perry wore this sheer striped dress best?

In 2010, Rihanna rocked a version of the sexy, form-fitting gown in red (to match her fiery locks, perhaps?) for New Year's Eve in Vegas, while Perry opted for black at the NARM Music Biz Awards in 2012. It's not clear if Rihanna's version of the dress is a Louise Goldin like Perry's, but the real-life BFFs are both sizzling in the bold dress.
