I have been asked to attend an informal interview for a business administration apprenticeship I really want, but its just at the local college. Do I still go smart? would a dogtooth skirt and blouse be okay?. Also I have quite an alternative look, especially with my hair as it is half red/black meaning one side is fully black and the other red. I want to wear a bun with fringe down but think this may exaggerate the hair, also should I take my piercings out. However Ive been thinking of leaving things, as its my personality and perhaps address the issue if its brought up? but I'm worried first impressions on appearance will put them straight off.
