I don't know what to wear tomorrow?

Well you don't want to vamp up to much as you will look a bit out of place and a bit to obvious! Just go smart casual - a pair of skinny jeans with ankle boots and a smart top would be fine, add some bling and do your hair and makeup nicely - this will give the impression that you take a pride in your appearance but don't need to be trashy and over the top to feel confident and y!
