someoneNew, people who are now buying $300 jeans will not revert to buying $80 jeans, they will simply start buying fewer pairs of $300 jeans and buy $300's worth of some other type of garment. Prices, which are like taxes, don't become lower once they've gone higher. There have been some brands (most notably, Paper Denim & Cloth) which have lowered their prices, but that was a conscious decision on the part of Federated to reach a different consumer. However, the number of brands available will become less as the market dries up and companies fall prey to attrition. I think that denim is still pretty strong, but I see the market tapering off somewhat very soon.
As for Nathan Bogle's new line, we'll see. After all, Earnest Sewn has sort of supplanted Paper Denim in that particular niche, and Paper Denim has been relegated to a second tier line. After Jerome Dahan left Seven, Seven continued to be strong, but it had to make room for Citizens of Humanity. It doesn't sound like Nathan Bogle is gunning for the same market as Rag&Bone, but you can never be sure. As I understand it, he was the spokesman for the group, but was not necessarily the driving force behind the brand, so we'll see about that as well.
