Speaking of cost delta between perceived "high end" and regular retail, I think the automotive biz has already set the future trend for all sectors of commerce, that is survivability. Take for instance the retail spread between a Ferrari and a Ford Focus. Retail prices are vastly separated but the same cannot be said about the OEM margin due to capital utilization and volume. The auto business has learnt this lesson over the past hundred years where only those offering quality at competitive prices survived. Some OEMs use the tactic of simply rebranding high volume cars and marketing them as high end but they risk exposing themselves to brand dilution [[Lexus= 90% Camry). Once the public understand that, they quickly opt for the logical alternative. Same IMO will apply to the $400 T shirt but I don't blame these retailers for having a crack at it.
