I took at trip to Berlin 1920s, an area reproducing the feel of Weimar Germany, the era between the wars, where inflation was turning into hyperinflation. Though the area is still under construction, it shows a distinctive style.
Stores display the opulence that was to be had in the Twenties - for the wealthy - while billboards and shabby alleys hint at the troubles the poor were having. (As a small aside, one wonders why politicians and constituents alike remember that recessions are bad, but tend to forget how damaging inflation is.)
The rules of the area say "Strict Dress Code!" which, to someone with an extensive Victorian wardrobe and not much else, can be a little intimidating. I donned a 1940s suit from Ingenue, and I seemed to fit in satisfactorily.
