What is a suitable gift for an Italian PhD advisor based in the UK? This question is already asked here. But I found the answers unhelpful, so I would like to ask again, and narrow to the case the advisor is Italian (but has lived in the UK for 20 years).

I would like to buy a gift, so suggestions such as in the accepted answer "be someone who is easy to advise" is not helpful. I already finish my PhD anyway.

I am thinking of possible options:


Chocolate (sound informal)
Shirt (I don't know his size)
My PhD thesis with beautiful hard-bound cover (I doubt that he will ever read it again)
...


Please give me some suggestions. I'm an Asian, and do not know much about European traditions. At first, I intended to invite him (and all people in the group) for a drink on my viva date, but it turned out he insisted to pay for all :(
Instead of something related to Italy, how about something related to your own home?  I (in the US) had a student from China; she gave me a tapestry depicting the Great Wall.  I still have it hanging here many years later.


  Important note: you have finished the Ph.D.  Giving gifts before that may be seen as an attempt to bribe him.  It seems to be the custom in China and Korea to give gifts to the professor, but not in the US (probably also not in the UK).  Wait until after you are finished, so it won't be seen as an attempt to unfairly influence the professor.
