Cocktail attire for men is a dress code that is less formal than black tie but still requires a high level of polish and style. It is usually worn for events such as weddings, receptions, parties, and anniversaries. Cocktail attire sits in the middle of the formality spectrum, and it allows for some personal style. The following are some guidelines for mens cocktail attire:

• Suit or blazer: A well-tailored suit jacket or blazer in dark, versatile colors like navy, charcoal, or black is a cornerstone of cocktail attire for men.

• Pants: A pair of well-fitted, tailored pants in classic hues like black, charcoal, or navy blue is a standard choice for mens cocktail attire.

• Shirt: A classic white dress shirt is a perennial favorite since its versatile and timeless and goes well with any suit. An Oxford shirt is also a good option for a more casual look. Formal-looking sweaters and long-sleeve polo shirts can also be suitable.

• Neckwear: Neckwear such as a necktie or bow tie is expected. A black satin necktie is a classic choice.

• Shoes: Dress shoes such as Brogues, Oxfords, or Monk-Straps are appropriate. They should be well-shined and match the color of the suit.

Overall, mens cocktail attire requires a high level of polish and style, and it should not read casually. It is less formal than black tie but still requires a suit or blazer, dress pants, dress shoes, and neckwear.
