Like I said here earlier, in Buenos Aires, there are very few malls like the one below- Galerias Pacifico. I have posted my pictures during my previous trip here.
If you are looking for gorgeous Tango dresses, I highly recommend Tango Imagen. Right next to it is another good shop for tango clothes. In tango imagen shop there are names of dresses and skirts - like tanguero, milonguero, etc.
In San Telmo, there is this gift shop selling artifacts of tango.
While I was in San Telmo, I revisited the apartment that I stayed in, in my previous visit. It is in Peru-1102.
The road across is called Humberto
This road leads to Dandi Mansion, where CITA tango festival was held.
