The occasion is seen as a dress rehearsal for a girl's wedding day.
However, when she arrives at church, it soon becomes apparent she is sharing the communion with her non-gypsy schoolfriends, who are bemused by her over-the-top dress - inspired by Lisa Dowell's wedding dress in Eigthies movie Coming To America.
Marriage signifies a change in position of the married couple in Roma society as full and productive members of the community. The customs and rituals for engagements and marriages described here are traditional and vary for the many Roma tribes around the world.
Engagements In spite of myths of Roma immorality, most Roma follow strict rules of sexual behavior.
Records cannot identify exactly why the Roma migrated from India; there are a number of possible motives, such as famine and military invasions on the part of Alexander the Great (356-323 BCE) and/or Mahmud of Ghazni (971-1030 CE).
For this reason, they are accompanied by great celebrations.
In the run up to the wedding, the couple aren't allowed to be together without a chaperone, with Josie explaining gypsy girls can never be alone with a gypsy boy because it would ruin their reputation.
She said: 'When I first seen them, it was like "My God…" They did look like prostitutes - that’s how you would describe them…
But it is a worse violation of the marimÃ© code for a Roma female to marry a gadjo, because Roma women are the guarantors for the survival of the population.
In the case of a mixed marriage, many tribes consider the children Roma only if the father is Roma.
