MILAN — The tony Montenapoleone district of luxury boutiques in Milan reopened Monday — but no shoppers were in sight.

The shopping district is home to such Milan fashion mainstays as Armani, Versace, Ferragamo, Fendi and Bottega Veneta, but most sales are to foreigners — primarily Arabs and Americans, according to official figures — who still are not able to travel to Italy.

Air traffic remains severely limited and a 14-day quarantine on arrivals in place until June 3.

Meanwhile, nearby at city hall, hundreds of open-market vendors were protesting the failure of the city to come up with rules for non-food stands to reopen.

“They haven’t worked for three months. What are they going to do if they can’t reopen — steal, go ask charity?’’ said Nicola Zarrella, the vice president of Euroimprese, which represents 22,000 market vendors in Lombardy. “They want to work, not get handouts.”
