The dresses in the pi.collection emphasize the well-being of the wearer's body and lend it elegance and presence. Functionality emphasizes feminine flexibility. Models made from sensual materials with an individual fit that can be combined again and again become classics in a wardrobe.

The collection concept does not follow the usual, fast cycle of the fashion industry. Since it was founded in 2005, pi.collection has been a slow fashion label: consistency, quality, fair working conditions for tailors and local suppliers are the credo.

Fashion designer Pia Herrmann runs her label pi.collection with its own in-house studio & production at Bahnhofstrasse 20 in Uster.
