The staff at Maine College of Art, aka MECA, isn’t hindered by the mundane khakis and personality-less button-up shirts that plague many offices. Artistic license reigns here. Personal expression? That, too. The hallways at MECA see colorful brooches and patterned skirts, shiny blue shoes and tees decked with cassettes, or head-to-toe black with just a hint of white birds – and that’s just the people who work there.
