Hi Adam!
I Heard you're been invited to the wedding in Poland. I would like to give you some advice on what to wear to this wedding. You have to wear for example: suit, tie or bow tie, elegant shoe, or something similar.
Everything starts when all guest came to the church. Later when ceremony ends you need to come to the restaurant. Don't forget to buy the leaving presents for bride and groom. Maybe toaster or something for house.
Write back and tell me what do you will buy.
bye,
XYZ
