Personally if I were in Naples I'd be looking for dead stock fabric. I recall seeing discontinued Scabal Shetland at Argenio. I'd love to see if I could find old Wodehouse or other discontinued cloths. OTOH you kinda need to know what to look for. I'm not sure if Carlo Barbera sells to the public now they have been bought by Kiton. It would be nice to find some deadstock.
