Taylor Swift looks lovely, but her dress is SO sophisticated that it's hard to take her seriously. Her body is composed, but when they cut to her face, she's barely more than a teenager.
I'm really into people dressing their age. I know, I know. Even as a kid I sure wanted to play dress up like an adult. But that was in my parents garage, and there wasn't a camera on me.
These days, young people from 15-24 dressing like they are 35 just look silly to me. There is no mature sexuality going on there, trust me. Maybe they "know" a lot, but they don't know what they are GOING to know in about ten years and there is nothing you can do but wait and get there to know what I am talking about.
I say ENJOY dressing like you are 23, if you are 23. You sure can't dress that way when you are 35 without feeling/looking just a little silly, too.
