She's right... well kinda. Did some snooping on google and from what I know before, Seven is owned by VF Corporation, but i just found out they made a deal to buy RR's trademark and start putting their stuff into Kohl's.

Apparently RR filed for chapter 11 two years ago.
Being in the garment business before, I can tell you the denim market is a highly risky business to get into. One day you're the hottest brand on earth, next day you're clearing your stuff out at pennies to the dollar and selling out your name to survive. But I have to agree Diesel is one of those premium brands that have withstood the test of time.
I like to try all brands of denim and lately I've been slimming down my jeans (the style and the collection) a bit and I have to say my favorite pair so far has been PRPs. Expensive, but superb quality. Also have a pair of APCs in raw selvedge and they're broken into very nicely.
