The dresses for the girls must be in the same color and style just as the suits for the boys are in the same color and style.
The reason for this is that all eyes will go to the birthday girl on that special day.
Then the family orders a cake that is special like a wedding cake.
Sometimes the godparents pay for it. Many times,the cake is so big that it needs a special table.
Next, the parents rent a hall for the party and rent a band to play music.
