Hard pass on dance shows... haha. TBH I rarely see it even in the weddings I attended in Indonesia, and my wife and I prefer the minimalist way people in Sweden get married - no extravagant parties
Batik, could be. Like Indonesian cuisine, it's also strictly speaking not uniquely Indonesian though
But just as ethnic boundaries tend to be seen as less significant among Indonesians abroad compared to in Indonesia, I suppose the same is also true of national boundaries - who cares if, say, a restaurant or a dish is Malaysian, Singaporean, or Indonesian - it's rare enough to see any here.
