Cocktail costume, commonly referred to as after-five attire, is intended to be worn to semi-formal occasions outside of the workplace, such as gatherings or romantic dinners. For men, pants, a button-down shirt, a blazer, and an optional tie make up a suitable after-five look.
While there are some similarities between after-work wear and work attire, males can be a little more daring and flashy in their colour and pattern choices while dressed for after-work events. Contrasting-colored ties, vests, and other accessories are permissible. Although it is not necessary, wearing a jacket is recommended, especially for evening events.
