What is the difference between formal and black tie?
In both formal and black tie events, women typically opt for floor-length gowns or refined cocktail dresses. These garments are characterised by their classic and timeless designs, often featuring fine materials and exquisite detailing.
However, the key difference lies in the level of detail and strictness associated with the black tie dress code. At black tie events, a higher degree of formality is expected, and this usually means avoiding dresses that show your ankles.
