5. Take out your best china — but don't be afraid to mix it up with fun, casual pieces. Even if your dinner party is more formal than casual, add a note of levity to the gathering by pairing bold napkins with your delicate, wedding-registry china. And don't wait for another "perfect occasion" to break out the Noritake plates or Wedgwood tea seat — there's no better time than the present to treat your guests like royalty; show them by serving them their meal on your best dinnerware.
