This largely depends on the position for which you are applying. Otherwise looks to be going to talk to a large corporation, and otherwise for the position, eg. in a tattoo studio (here you can keep more slack and originality) and fitness club. There should be always some touch of elegance, but becoming engaged in office work, it is best to put on the classics, blouse, jacket, pants/skirt and high heels. It is worth remembering that the skirt was not too short (preferably to the knees) and a blouse cut too deep (preferred a little cleavage). Colours is now optional. Black and white is associated with the school, so it’s woth to revive such a costume. A grenade and bile are now in fashion. Dress should reflect your personality – it works!
