Congrats that you've finally decided this area of your life is worth some effort!
You've come along way little one.
Fashion can be really fun when you get into it. When you start finding clothes that look really good on you and fit well you'll really start to enjoy it. I know I did. It's also fun looking in the mirror and seeing someone dressed well looking back, especially if you're not used to it.
Oh, get a haircut too.
