A beautiful sport coat but I really hate that Isaia branding thing in the lapel button. It's like the Ralph Lauren polos. Why do you need to proclaim the brand, the coat clearly speaks for itself.
I would have also gone for a white pocket square or perhaps a navy/green or navy/brown paisley silk one.
I went off sport coats and jeans because I feel I am too old to pull it off, but you should stick with it.
Nice to have a pic of the coat unstructured, or unlined, on its own. Good look.
