Whichever metallic you chose, just don't overdo it. You can wear metallic shoes and a metallic bag if, and only if, the shoes are strappy sandals and the bag is a small clutch, but it's better to pick one, either shoes or a bag, not both. And don't forget to adjust your jewelry to reflect your metallic shoes or bag. If you're wearing silver shoes, stick with jewelry in a white metal like silver or platinum, for gold shoes yellow gold jewelry is best and rose gold shoes will go best with rose gold jewelry or copper jewelry. But keep the jewelry minimal. A metallic accessory will stand out on it's own.
