Cleaning anything. Washing your car on the weekend? Cleaning the oven? Bleaching the shower? Take off that rock. That’s especially important if your ring has a colored gemstone rather than a diamond, as the chemicals can erode the finish and polish on the gem.
The formal dress code is located somewhere between cocktail and black tie. For the ladies this dress code requires a short or long formal dress, a pantsuit, or dressy separates. For men, a dark suit, white shirt, and conservative tie is appropriate. Men can opt to wear a tuxedo if they wish, as the formal dress code is really another way to describe black tie optional.
Black tie is the second most formal dress code and is typically reserved for evening weddings. Despite what its title may suggest, black tie does not mean you must wear black, although traditionally men should wear a black tuxedo and a bow tie. Black tie appropriate attire for women can be an evening gown of any colour.
