Josh Le, University Of Alberta Student, Wears Same Pair Of Jeans For 15 Months

Good news: Turns out that wearing the same pair of jeans every day isn't hazardous to your health.

University of Alberta student Josh Le wore one pair of tight, raw denim jeans for 15 months starting in Sept. 2009. At the end of his trial, he and his professor, Rachel McQueen, found that the most bacteria accumulated in the crotch area of the jeans -- 8,500 to 10,000 bacterial units per square centimeter -- but overall, the pants were still safe to wear.

McQueen said that the bacteria levels in the jeans were similar post-wash and pre-wash.

Le isn't the first to attempt such a clothing challenge. Last year, Sheena Matheiken discovered an untapped font of sartorial inspiration through wearing the same dress every day for one year in a challenge she titled the Uniform Project. Matheiken, however, washed her dress.
