What is a black tie wedding guest dress code?

Black tie is reserved for evening weddings, usually starting after 5pm, often in grand venues like hotels, castles or banqueting halls. For men, the standard is a black or midnight blue tuxedo, also called a dinner jacket, with a white dress shirt, a black bow tie, and black patent leather shoes. A cummerbund or waistcoat is optional but traditional. You should not wear a regular suit, a coloured shirt, or a standard tie. For women, a floor-length gown is the classic choice, but a very elegant knee-length or midi cocktail dress in a rich fabric like velvet, silk or sequins can also work. Avoid casual fabrics, bright casual prints, and anything too short or too casual. Jewellery should be dressy, such as pearls, diamonds or crystals, and shoes should be heels or dressy flats. A clutch bag is appropriate. If the wedding is in a place of worship before the reception, check whether you need to cover shoulders or arms, and bring a wrap. Black tie is about elegance and attention to detail, so make sure your outfit is well fitted and your shoes are polished. If you do not own a tuxedo, you can hire one, which is common in the UK.
