I highly recommend it for shopping!
You can buy everything here! The choice of clothes is excellent. There are two separate buildings for men and women.
The Vesna department store on Boulevard Haussmann in Paris is large, ancient and famous.. It differs in that there are much more luxury brands here than in neighboring Lafayette and, accordingly, there are fewer people and it seems more spacious. There is a good observation deck with restaurants on the roof, but it is quite expensive there and free places are usually reserved in advance. But it doesn't hurt to take a couple of photos. In a word, for an amateur and the owner of a thick wallet)
