British star architect Sir David Chipperfield designed the six-story P & C store. With the longest facade on the Kärntnerstrasse, huge windows, and almost a complete lack of ornamentation, it can't be missed. Find the best-known fashion labels, as well as inexpensive off-the-rack garb. Shop to the grooves of a live DJ every Saturday from 11 am to 6 pm. at the Mariahilferstrasse location.
