Alyson Hannigan FHM cover (click here)
Now I don't so much mind Alyson Hannigan, aka Willow from Buffy: The Vampire Slayer (not from Willow the movie staring Warwick Davis). I in fact like her a lot in a certain geeky, Eddie-Munster-widow's-peak freakish way. Considering that she is a red-head and played a geek (a band geek, but still a geek nevertheless) there's a sort of innocent appeal to her, even though she is more rough around the edges than you would think. However in this lovely cover shown above it is obvious that she fell victim to a wandering air-brush pen.
I could see how someone would want to add definition to her cheeks, but it just ended up making her look 40 than mature. I guess in someways, FHM was considering to not look like a "Just 18" porn mag.

Shannon Doherty
I never really seen the appeal to her. Sure she was brunette and had a bitch streak that created some kinda fantasy of dominatrixs, ankle lenght boots, whips and a french baguette. However the problems is that in this picture, she fucking ugly. Yes I have the gall to say that cause if a sign of being sexy/physically fit/evolutionaryly great is how symmetrical your face is. Denzel Washington has the most symmetrical face in high-tier hollywood. But as you can see with Shanno here, her face looks like her ass, sagged to one side. granted if you were to cover one half or have a mirror, it might look better, but that lazy eye actually makes her look like she has down syndrome or something shit like that.
