Ok, I don't know about Thailand traditions, but for a regular wedding you are going to need money for the rings, dress, veil, shoes, garter, suit, church or hall you marry in, the cake, flowers, food, drinks, plates, decorations, tablecloths, napkins, party favors and music. And that is just off the top of my head. If she wants it catered, and with live music or a DJ, you are gonna start getting expensive. Also, it depends on what you are serving people to eat, and how many are coming. Isn't this so cool, I love weddings! And of course, lots of money for film, cause if I don't get picks, thats it mister. 😉
