3. Formal / Black Tie

   Gowns, tuxedos, and upscale accessories are essential.

👗 Women’s Styling Essentials

• Velvet blazer + tailored trousers

  Festive fabric meets structured tailoring.

• Knit midi dress + ankle boots

  Comfortable yet refined for winter.

• Satin or metallic wrap dress

  Minimal effort, maximum impact.

• Jumpsuit with statement jewellery

  A sleek and modern alternative to dresses.

Add seasonal touches through jewel tones like emerald, burgundy, navy, and luxe textures such as velvet or satin. Keep sequins and sparkles tasteful for a professional setting.
