Riefensberg is a municipality in the district of Bregenz in the westernmost Austrian state of Vorarlberg.

The town of Riefensberg ("rivinsperc") was mentioned for the first time in 1249, in a document by Pope Innocent IV.

In the Juppenwerkstatt Riefensberg, traditional Bregenz Forest costumes are still dyed and sewn.

The typical "Bregenzerwälder Juppe" is not sold "ready-made" in shops, but can only be custom-made in the Juppenwerkstatt.

Nowadays, many Bregenzerwälder women wear the Juppe at weddings and in church on Sundays.
