In the era of Photoshop, pictorial evidence gets less and less trustworthy.
But in the case of Vicky Little or Melanie Tipps, there always was the little revealing smudge where the latex breasts were fixed to the body.
In the case of this lovely chinese lady, this seems to be missing.
So, either a better makeup artist, photoshop... or legit.
