The state attorney general's office has recently received a significant amount of complaints about clothes that look to be name brands but aren't, Blumenthal said.
The clothes are being sold on street corners, in consignment shops and at athletic events, including at UConn games, Blumenthal said.
Counterfeit clothing is a difficult crime to prosecute, Blumenthal said. Counterfeiters are constantly on the move and can be difficult to track down, he added.
Consumers can protect themselves by buying directly from reputable retailers.
Another key is to look at the tags on the clothing, Blumenthal said. A faded or removed tag can be sign of counterfeiting.
