Melania Trump: Topless Mural Takes Dig at Hillary Clinton (PHOTO)

Melania Trump's going topless Down Under on a giant mural ... and it doesn't look like the artist is much of a Hillary Clinton fan.

Melbourne street artist "LushSux" slapped up the potential future First Lady on an alley wall, and jacked Clinton's unofficial campaign slogan -- "I'm with her" -- for the piece.

The boobs DO appear to be Melania's and not Michelle Obama's

If the work looks familiar that's because "LushSux" previously did a version of Kim Kardashian's naked selfie in a different alley.
