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.
White tie, also known as full evening dress, is the most formal dress code and is suited to an evening wedding beginning after 6pm. Men should wear patent shoes, trousers with a stripe of satin on either side, a double breasted evening tailcoat with a white shirt, a white waistcoat, and white bow tie.
Hitting the gym. Wearing your ring during cardio activities won’t do it any harm, but it’s the weight lifting that can take a toll. The pressure of the weight’s bars (or really, any amount of strong pressure) that’s applied to your band might bend it, which is especially bad for a pavé band because the smaller stones can fall right out of their setting. As for contact sports, definitely take off the ring, or risk a serious injury thanks to ring avulsion.
