Black tie has loosened everywhere except on invitations, where it still means floor length. The result is a guest brief that reads strict on paper and vague in practice, and most people over-correct into gowns they will wear once. This edit sticks to the three things a black tie dress code genuinely rewards: embellishment, floor length and colour that holds up under bad lighting.

Embellished and sequined
Sequins used to be a New Year's Eve problem and are now the safest read on a black tie invitation. Embellishment does the formality for you, so the shape underneath can be as simple as a slip.

Gowns in black and navy
Black and navy are still the least risky answer to a formal dress code, and the argument that guests cannot wear black to weddings has quietly collapsed. What matters is that floor length reads as respect for the invitation.

Floor length, in colour
Colour is where black tie has actually changed. A saturated gown now reads as more considered than another black column, and it photographs better in a room lit entirely by candles and phones.

Our honest take
Black tie is the one dress code where guessing down is worse than guessing up, so if the invitation says it, go floor length and stop negotiating. Rent or buy, but be honest about the second wear before you decide. If you take one thing away, hem length is the rule and everything else is preference.
