The main objective of an outfit like this is to look goo while being toasty warm. I think this skater dress by Louise Goldin for Topshop is quintessentially skater date and is sort of the centrepiece of the outfit. I would layer another skater skirt in a complimentary colour (this one's silver) underneath for added warmth and interest.
I'm digging chunky snoods as an alternative to scarves, and you don't have deal with getting your scarf caught in your skates. The wooly legging add texture and the legwarmers could be use as arm warmers. The coat is warm and funky-utilitarian and the high tops add a dash of colour.
