Get Buzzed In
Locked shop doors are standard anti-theft practice, so don't be surprised (or intimidated) by having to ring a doorbell and be buzzed in. Once inside, you’ll find that sloppily dressed customers usually get sloppy service. Porteños (as residents of Buenos Aires are called) take shopping seriously, and they dress for the occasion. You should, too: ditch the sneakers and fanny pack and look like you mean business.
