St Paulsgatan 3, just a 5-10 minute walk away. It is also conveniently located just 10 meters away from the semi-pedestrian street Götgatsbacken, where you will find a plethora of other shops... including many other Swedish designers (everything from H&M to Filippa K).
Biblioteksgatan 6 in the downtown area. If you are looking for a deal, then I can recommend a visit to their outlet store at Stockholm Quality Outlets in Barkarby where you can find last season's fashion for up to 70% off the regular price. (all pictures in this article are by me!)
