Jember Fashion Carnaval or JFC (Indonesian Karnaval Busana Jember) is an annual carnival held in the East Java city of Jember. Officially it is written as Jember Fashion Carnaval; the word carnival here is officially spelled as carnaval, probably a confusion with Indonesian spelling karnaval, or an influence of the Dutch spelling carnaval. Jember Fashion Carnival has no relation with the Christian pre-Lenten festival, but more of a festivities in general, roughly following the Brazilian style and the Canary Islands style, with procession of dancers in extravagant costumes, with emphasis on the traditional Indonesian motif.
Generally, the carnival used world-themed fashion or nature-inspired theme. Preparation was held extensively months before and participants volunteered for the event.
