What do owners of famous Japanese brands wear?

Would’nt it be interesting to know what kind of Jeans the owners of famous Japanese denim brands like Sugarcane,Flat head, Iron Heart etc wear ?

Well just came across this video on youtube which shows the jeans worn by the owners of these brands and the length for which they wore it..Though the video does not give very good closeup of the jeans, one can just have a feel of the jeans.
Another interesting thing to note is the average period in which they washed their jeans.. It differs -From 15 days for Iron Heart owner to more than 2 months for Flat Head owner..Goes on to show that there are no set rules when it comes to washing ones jeans..
