Black tie calls for floor-length. Whether the invitation reads “black tie” or “black tie optional,” the safest read is a full-length silhouette in an evening-weight fabric — silk, satin, or a heavier crepe that holds its shape through a long reception. Our black tie edit is built from the same upcycled silks and fabrics used across the rest of the collection, in colours that carry from a ceremony into the evening: black, bordeaux, deep green, champagne.

Black Tie, or Black Tie Optional?
A strict “black tie” wedding guest dress code has one real requirement: floor-length. Colour is more open than the name suggests — black, navy, and deep jewel tones are all correct, and a fully black dress is a traditional, entirely acceptable choice, not an oversight.
“Black tie optional” — sometimes written “black tie preferred” or “black tie invited” — gives a little more room. A long dress is still the safer choice, but a well-structured midi or an elevated cocktail-length dress in a substantial fabric, not anything casual or unlined, reads correctly here too. When in doubt, floor-length is the choice that never overdresses a black-tie-optional room.
Choosing Length and Silhouette
Floor-length remains the standard for a reason: it’s the one length that reads as formal from every angle, in every room, from a seated ceremony to a standing reception. A column or A-line cut in a fluid fabric moves easily and doesn’t require constant adjustment through a long evening. If the invitation allows more flexibility, a long midi with a defined waist and a structured neckline — rather than anything loose or unlined — carries the same level of formality in a shorter length.
Silk and silk-blend fabrics hold their drape without clinging, which matters for a dress worn from a seated ceremony through hours on a dance floor. A heavier crepe or satin resists the wrinkling that thinner fabrics show by the end of the night, and photographs with a cleaner line under evening light. Our black tie pieces are made from upcycled silk, viscose, and satin blends sourced from surplus fashion-house fabric — the same sourcing used across Gaâla’s collections.
Fall receptions tend to run indoors and after dark, which suits the deeper end of this edit: bordeaux, deep green, and black hold their weight in low evening light in a way that pale colours don’t. A long sleeve or a fuller silk overlay also earns its place once the ceremony moves past daylight hours.
Yes. Black is a traditional and entirely appropriate colour for both black tie and black tie optional weddings — it isn't read as underdressed or as a mourning colour in this context.
Do I have to wear a floor-length dress?
For a strict black-tie dress code, floor-length is the standard. For "black tie optional," a long midi or a structured, elevated shorter dress is acceptable, though floor-length remains the safer choice.
What's the difference between "black tie" and "black tie optional"?
"Black tie" expects a floor-length gown. "Black tie optional" (or "black tie preferred," "black tie invited") allows a little more flexibility in length, provided the fabric and construction still read as formal rather than casual.
