Dress code

  • No formal dress code in the city; smart-casual covers almost everything.
  • Some upscale restaurants, theatres and clubs discourage sportswear and trainers in the evening.
  • Cover shoulders for religious sites such as mosques and gurdwaras; Westminster Abbey and St Paul's are relaxed but respectful dress is expected.
