Lounge suit, sometimes written as business formal or simply formal, is common on UK wedding invitations, formal daytime events and some race days. Despite the name, it isn't relaxed: it means a matching suit with a tie.
What to wear, piece by piece
- Jacket
- A matching suit in navy, grey or charcoal. Two-piece is standard; a three-piece adds a little extra polish.
- Shirt and tie
- A pressed shirt in white, light blue or a subtle stripe, with a tie. The tip of the tie should land at the middle of your belt buckle.
- Trousers
- The matching suit trousers, hemmed to just touch the top of the shoe.
- Shoes
- Polished black Oxfords are the safest choice; dark brown Oxfords or Derbies work for daytime and country events.
- Extras
- A pocket square, dark socks that match your trousers, and a belt that matches your shoes. With a three-piece suit, wear braces instead: no belt under a waistcoat.
What to avoid
- An odd jacket and trousers.
- Trainers of any kind.
- Leaving off the tie.

Quick questions
Does a black suit count as a lounge suit?
Technically yes, but navy or grey look better in daylight and are more versatile.
Can I take my tie off later?
At weddings, usually once the evening reception starts. Follow the groom's lead.
What does lounge suit mean at the races?
A suit and tie, often with a little more colour or pattern than at the office. Check the enclosure's own dress code too, as some are stricter.
