Your example of Penelope Garcia from Criminal Minds is either excellent or wrong, depending on your viewpoint. The reason I say this is that one of may favorite things about Kirsten Vangsness (aside from being born on my birthday) is that her character's wardrobe is HER PERSONAL wardrobe. way back in the first season, before she became a full cast member, she had some kind of conflict with the producers because the real FBI would absolutely NOT let an employee get away with several of her clothing choices. They decided that, with her character being the Goddess of the computer world, that she'd be allowed more leeway than in real life. So she didn't know what to wear and just came in in her regular (for her) clothes. The show people said "Perfect!"
On the other side of the equation, I have noticed a few guys on TV who kind of look like me. My sister thought it was hilarious that 'Uncle Phil' from the Fresh Prince of Bel Air looked a lot like me, even though I'm an exceedingly pale white guy, and he was a medium-light black guy. I suspect it was the bald head, short beard, and general physical similarity she was pointing out. I've also noticed that TV guys who look like me are either 'married for decades - so don't think about them still doing it' or 'hopelessly, desperately alone till shortly after the end of the universe'. As you might guess, this bothers me. Sadly in real life, I'm both. I was happily married for twenty two years. And I've been morosely widowered for two and a half. Unfortunately, just like on TV, it's hard to get anyone to see any appeal in a 53 year old large bald guy as a romantic possibility.
