The Vaad L’Mishmeres Shatnez has reported:

As the Centurion brand suits are manufactured in China, scrap materials are being put into each and every suit. As such, it is incumbent to test for shatnez at a competent shatnez laboratory, each and every suit before wearing.
Below is also a picture of a dart with linen threads, that was discovered in a Centurion woolen men’s suit sold at His Place in Lakewood. The consumer was told by a salesman that the suit needs no testing, he had it tested for shatnez regardless – and shatnez was found!

Many other stores are also having serious issues with shatnez. One should be careful to test his woolen garments before wearing them, regardless of the advice of the salesperson.
