Sexy jeans, a nice simple top, casual but smart and also a bit fun so i would go with Pink Fizz, a colourful vesty type top would be good, or even a halter top if it's not too going outy type. I wouldn't wear boots, but it depends how comfy you will feel, maybe some wedged sandals, or funky flip flop, kitten heels or something like that. make sure your toesies are looking nice though.
A little make up to lok like you have made an effort, but not too much, and the same with jewellery I think. Maybe more beads and simple bits and peices.
