This is something I was thinking on too. We don't need a world dedicated to weddings, and surely the Devs are aware of it. But without the world, it's mostly a Stuff Pack with some renamed Parties. In fact, despite people wanting Weddings touched up a bit, I think they would have settled for a Stuff Pack.
While it has quite a few items, there's a lot of skins - not a whole lot of new mediteraneen items for a mediteraneen world - and keep in mind how there's only one veil - despite the high number of wedding dresses, even though a character can only wear a wedding dress once.
