From the Boston Globe:

Pop star Katy Perry is sporting a skin-tight minidress with President Barack Obama’s campaign slogan ‘‘Forward’’ emblazoned across it at the president’s rally in Milwaukee.

Perry came on stage at Saturday’s event initially wearing a red, white and blue dress and holding a microphone shaped like the Statue of Liberty’s torch.

But after her first song, a cover of Al Green’s soul hit ‘‘Let’s Stay Together,’’ she tossed aside the dress to reveal the bright blue minidress.

Obama’s slogan ‘‘Forward’’ is also Wisconsin’s state motto.
