The brand I Levrieri actually means, "greyhound" in Italian. The products are popular in Italy with a TM registered in the United States in 2007. They are owned by LUCA MAGLIERIE S.R.L. a clothing manufacturer.
They are a good brand. I myself thrifted a cashmere sweater today. I'd bought a similar one at Saks marked down from 472 and then returned it because I couldn't afford it. This sweater cost me about five bucks. Not bad and I'm very very happy.
