What did you do for your 18th Birthday?

I have been dreaming of finally becoming an adult for years. Being a larger girl all my life, I always wanted to be "skinny" for this special day. I know it sounds crazy but I just wanted to be able to go out with confidence. Now my body is smaller than its ever been and I am so excited to celebrate my birthday!..I just have no idea what to do.. OR what to wear!!! I need help, ideas, what did you do?, did you order an outfit off a website?, do you know of any generally affordable websites for rockin' outfits? did you go out at midnight or save it until your actual birthday? something to help inspire me for what I want to do! Every plan I make so far has fallen through and I have 3 weeks to make my 18th a day I won't forget! Pleasses help a girl out xox
