There are a few different "Outfit Formulas" you can keep in your arsenal. This is just a guideline you can play with. Don't have a colored jacket? Make your bottoms be the pop of color, or your shoe instead and fill in the other pieces around that. Often times my earrings or a scarf is my pattern. Pick the piece you want to wear today the most and build your outfit around it using these elements.
