A crook used a cobblestone to smash a window at a high-end Italian fashion shop in the West Village — and looted $15,000 worth of merchandise, an NYPD spokesman said.

An unknown man used the stone to break the front glass window at Tiziano Zorzan around 3:30 a.m. Sunday, and cut himself as he entered, cops said. 

A 39-year-old employee at the fashion shop told cops he was alerted of the theft by his security alarm company.

The burglar removed about $15,000 worth of “fancy clothes,” mostly coats, the NYPD said.
