American singer-songwriter Katy Perry was spotted rocking a black Thrasher Snapback Cap by Adidas when she arrived at LAX airport last February 13 with matching all-black outfit. The camera-shy singer was seen arriving at the LAX airport en route to a nearby studio in town. Katy Perry pulled what we would call a fashion no-no matching the cap, with training pants AND sneakers. Someone should give her a lesson in over matching. The cap is available now online at Urbanoutfitters.com.
