This outfit could work in so many different environments, including a casual office, which is what makes it so perfect. Run to the office, run some errands, stop for drinks - all without worrying if your outfit is appropriate. For a more formal look, simply take off the vest.
Many people say leggings shouldn't be worn as pants, but
unless you're this woman I say GO FOR IT! Yours truly does it at least twice a week.
