The most useful formal dress is one that earns its cost-per-wear across several different events rather than a single occasion. To achieve that, prioritise a solid colour over a print - deep jewel tones, navy, black, and champagne all travel better across different event types than a pattern that reads as occasion-specific. A long-sleeve or three-quarter sleeve midi in a rich colour and a structured fabric is one of the most versatile formal dresses available: it works at a charity gala, a black-tie dinner, a corporate awards evening, and a formal wedding reception without adjustment.
For a non-dress alternative that carries the same formal register, a wide-leg jumpsuit in a deep tone with considered accessories translates as equally formal with a sharper, more contemporary edge.
