Dean Winchester is dressed in Lucky Brand 361 Vintage straight-leg jeans. These were first produced in 1951 by the L.C. Smith Company, which was later acquired by The Levi Strauss & Co. company. They are considered part of the vintage clothing movement because most people buy them for their unique look and not because they need to be maintained like modern clothes. Lucky Brand has become one of the most popular brands on TV series such as "Chuck" and "The Walking Dead". The show's producers have been quoted saying that they prefer using branded clothing due to its quality and longevity. This explains why Dean wears only these kinds of jeans. Additionally, he is often seen wearing shirts with his employer's logo on it. These include a Des Moines Police Department uniform shirt in the first episode and a sheriff's badge shirt in the second episode. It is known that both shows take place in Iowa so these items are appropriate. Finally, Dean is also seen wearing plain white T-shirts without any logos on them several times throughout the series. It should be noted that these T-shirts are never dirty or stained despite being used as weapons several times.
