How to do it

  1. Ask the couple early which events they hope you will attend and what costs to expect.
  2. Order or rent the outfit and get it fitted by the date the couple sets.
  3. Put the rehearsal, any parties and the wedding day timeline in your calendar.
  4. Arrive early on the day, dressed and ready when the photographer needs you.
  5. Help guests to their seats, carry things and run errands when asked.
  6. Stand still, face forward and keep your phone away during the ceremony.
  7. Help with setup or cleanup if asked, and make sure anyone who has been drinking gets home safely.

Common mistakes

  • Saying yes, then finding out the costs in the last month.
  • Missing the fitting deadline.
  • Treating the day as your party instead of theirs.
