I don't know about a makeover, but it was common knowledge in the PB model fan groups that Alley's post-pregnancy stretch marks were so horrible that body makeup didn't cover them properly. With her complexion (tanning) and her size, she was grossed out by showing her tummy. There was some photo floating around at one point that supposedly showed her with them, and it was rather bad--her baby took a toll.
I am guessing the quality of photoshopping these days would take care of that. Hell, Samantha 38GGG has all her photos so shopped she hardly looks like herself (her personal website, not the previous Bangbros or Scoreland pics).
