I finally managed to visit the Pradasphere at Harrods yesterday, and can’t recommend it enough. There is a beautiful collection of clothes and accessories from the last twenty or so years, with a particular focus on the collections of the last few years. It also offers an insight into the world of early 20th century Prada, with beautiful little antiquities on display.
The only downside was the gathering of insular sales assistants who stood around generally being irksome. But aside from that, definitely try and visit before the end of the month!
