First date with a good friend?

We’ve been good friends for a year. She was interested in me when I was in a relationship this past year. We had decided last week to give the dating thing a go. I just don’t want it to be weird/awkward. How do you go from hanging out with your homey (almost every weekend) to dating? Sure we’ll bust out the slingbacks, fancy dresses, order plenty of ridiculously priced frou frou drinks, and have a “romantic dinner”, but, how can you go about making it different; special? How do you make that transition – from them being a good friend to dating them?
