There was a debate on the most recent episode of the Real World (my source for cogent cultural commentary) about whether the world is harder for little girls or little boys. Ultimately, it devolved into name calling and foot stamping, but there are definitely some things are more complicated if you're female.
Take dressing up, for instance -- if you never make an effort, a certain kind of desirable man will never notice you. You have to be Betty Draper to marry Don Draper, and even then he'll still cheat on you with nearly everyone woman who enters his office, even though John Hamm is guest starring on 30 Rock. Then again, his character seems to be unhinged -- maybe even more so than Liz, which is something -- which is a lesson to you: If ever you see a couple in which one partner is significantly more attractive than the other, that person is probably completely insane or totally unbearable.
BUT if you make too much of an effort, dress a little flashy one day, and then you'll attract the wrong kind of attention and be forced to live in a state of perpetual invasive awkwardness. Take for example today's adventure on the subway (of course, where else) when a generally jovial homeless man boarded the train and proceeded to declare that we were all beautiful white women (I was wearing sweats) but that his favorite was a averagely attractive but conspicuously dressed (short skirt and heels, she looked a little trashy but, again, I was wearing sweats) and then proceeded to spend the next two stops touting her charms to the rest of the passengers.
Moral of the story: Betty Draper would have been shamelessly catcalled on the subway. Liz Lemon would not. Because she is practical. But she only gets to date Don Draper if he's a basket case.
