Been to Cappelli today. The store was quite easy to find thanks to Unbelragazzo's directions (even though Rubinacci is no longer at Via Filagieri and the Spada store is now a different brand I don't remember (Borrelli or Cucinelli?). Patrizio is a really nice guy. Unfortunately, I'm a very shy person, and my spoken English is pretty bad, so I didn't talk to him as much as I would have liked; and I didn't feel comfortable snapping any pictures, besides one of the courtyard where the store is located.
I settled on two madders, two challis and two pocket squares. Might get one or two more ties if I have enough money left before I leave!
