Jewelry (earrings, necklaces, bracelets), belts, shoes and watches are accessories that should enhance your style.
Proportion, appropriateness and how the individual wears them are critical to the effect. Accessories should be a style enhancer only.
A tip to determine what does not work is when the accessory becomes the topic of conversation as in: “Did you notice her red shoes or did you notice that belt buckle.” Then, the accessories may be too much. Remember that you are the center of attention. Accessories are just to polish your shine.
