Semiformal
Semi formal calls for occasionwear with more flexibility than a formal evening event. Try a dressy midi, a jumpsuit or tailored separates. Men can start with a suit or coordinated jacket and trousers, depending on the invitation. Use the time of day and venue to choose the fabric, colour and level of detail.

Daylight changes the finish
Lighter colours and breathable fabrics can suit an afternoon ceremony. An evening reception may call for darker tailoring or a dressier fabric. Keep the invitation’s level of formality in both cases.
When a tie helps
Bring a tie if the invitation is unclear. A jacket, collared shirt and leather shoes give you a useful base while you confirm the host’s expectations.

Good to know
What's considered semi-formal wear?
A dressy midi, jumpsuit or tailored outfit can suit semi formal. Men can choose a suit or suitable jacket and trousers. Keep the finish appropriate for a celebration.
What are some good options for semi-formal and smart casual men's attire?
For semi formal, start with a jacket, shirt and tailored trousers. Smart casual may allow a less structured outfit. Check the host’s wording before leaving the jacket behind.
What should I wear to a cocktail wedding?
Choose a cocktail dress, evening separates or a suit with a dress shirt. A cocktail wedding generally calls for a more dressed-up finish than an informal daytime lunch.
What counts as formal wear?
Formal clothing generally has a more ceremonial or evening finish. Semi formal allows more flexibility with separates and lighter fabrics, while still requiring a dressed-up outfit.
