I’ve been fortunate enough to always work in very creative/casual environments, but as I prepare for my first day of work today I hope to make a conscious effort to keep my work day uniform distinctly different from my weekend looks.  That means dressing up more relaxed basics with exciting accessories and balancing tougher pieces (see here leather motorcycle jacket) with classically feminine pieces (full or pencil skirts will do).  Business suit be damned.
