Each episode of course features at least one wedding and some of the preparation that goes into that, but it is a show more about the life of an average traveler girl. Weddings just happen to be the most important day in their lives, and the most frequent, or only, time they will make contact with a person who is not a member of the traveling community, the dress maker. The weddings are events of ridiculously impractical extravagance. Thousands upon thousands of dollars are spent on dresses and transportation and venues, but that's just one part of the show.
A more significant aspect of the program is allowing the audience into their very fascinating world. They have episodes dealing with how boys live and interact with each other, the lesser but still extremely ostentatious event of the first communion, that marriage is expected of each and every young girl, and what every day life is like. They show these strange juxtapositions, like how the girls dress very scandalously and scantly, but are in fact very pious and will not even spend time alone with a boy if there is no one else around, and how they spend most of their day cleaning and doing chores. The whole community seems to be fixated on appearance, and what other people will think of them, that they should be impressed. That also plays a role in the extravagance of their celebrations.
If you're looking for another wedding dress show, this one may not be for you (as their dresses are completely ridiculous) but as a study of a people that we don't really hear or know a lot about, this is a really interesting show.
Also, they made an American version of this show, and I recommend that you not watch it, it's a rip off of the original, and not a very good rip off. The people in the show almost seem like they're just average Americans who say gypsy a lot. I didn't commit to watching the American version of the show, but the episodes I did watch seemed to place more importance on the drama and the dresses. The original is more about the people and their culture and less about their tempers and greed. And it's better.
