Cocktail parties are today’s’ trend wherein the people from the corporate world find a reason for drinking.
These parties are places where the people get informal and thus should generally wear suits with a tie. By the way, the colour of the fabric worn and the fabric type used may vary from one occasion to the other or may vary from season to season. I know that the time of the cocktail party also holds a clue about the fabric type to be used.
I’d say in case the invitation is through a phone call or an email after that, it signifies less formal nature of the party but if it’s a formal invitation so it marks a very formal party which demands a formal dressing up style.
The first thing which holds a clue about the cocktail party is the mode of invitation.
The dressing style of a person going for a cocktail party may depend on various factors. For a cocktail party some decorum has to be maintained. Men can wear a tuxedo or a coat or a blazer with a tie. Women can wear knee length skirts together with a fitting blouse or a halter neck shirt if the nature of the party is a bit informal. Although, in the event of formal parties women can pick business suits for dealing with high profile clients and management people.
When the nature of the party is quite informal therefore skirts made of wool alongside embroidered cardigan are good for winter evenings while spaghetti outfits are cool ones for summer evenings. Impression is the last impression, as they say.
