How to dress for a black-tie evening?

Tuxedo

If you want to adhere to the classic black tie dress code, then choose the traditional tuxedo, which is solid black in colour, is single breasted, has one single button, has a peaked satin-faced lapel, does not have vents at the back and is made from grosgrain fabric. A dark midnight blue is an acceptable, and equally suited alternative.

Cufflinks
Cufflinks are a must-have accessory for black tie attire. Cufflinks and studs add an individual touch to the formal wear. Go with gold, silver, platinum, onyx or mother
of pearl.

Shoes
Black-tie footwear is slim, minimal in decorations, and lightweight. Two styles are common for black tie attire: The formal pump, as well as formal lace-up. The pump is always made from high gloss patent leather while the formal lace-up is also acceptable in polished calfskin.

Black Bow Tie
The classic neckwear for a black-tie function is a solid black bow tie that is self-tied. Satin lapels are matched with satin silk bow ties and grosgrain faced lapels are paired with finely ribbed or pi`que fabric bow ties.

The Classic White Shirt
A classic white shirt is perfect for your black-tie outfit. The turn-down collar is the most classic style. Button-down collars are a no-no.

Accessories
Visible timepieces are technically not worn because black-tie events are not something in which timekeeping is a priority. Opt for a timepiece with a classic black leather band and a thin body. Another great option is a pocket watch. Wear black socks—nothing too woolly, preferably silk or cashmere.

Waistcoat or Cummerbund?
The waistcoat and the cummerbund are acceptable waist coverings for black tie attire. You can opt for either a single or double-breasted waistcoat. The classic choice for both is black—matching the jacket. Traditionally the cummerbund has upward facing pleats and is made from satin silk or grosgrain.
