Oktoberfest is the biggest party in Germany, but you've got to dress the part. In the run-up to this year's Oktoberfest, which will kick off on Saturday, September 16, Stuttgart designer Kinga Mathe unveiled what may be the world's most expensive dirndl, which costs a whopping $32,000. The price tag for the dirndl may seem shocking, but every item is custom made for each individual client with only the finest materials and precious stones.
