I’ve seen this double-layered sarong look (minus the hat) pulled off with great panache by Bengalis on East Danforth and the Woodbine in Toronto, and by Tamils and Malayalis (folks from Kerala, India) in the Rouge River neighborhood.
I myself have worn it (very occasionally) with espadrilles and a loose, ultralight cardigan. It works!
Love your latest non-western street fashion posts. I did a Yangon street style post a few months ago and it was seriously the only Yangon street style post ever. Now the Sartorialist does guy sarongs. Yay.
