Yves Saint Laurent’s Rive Droit brand has come under fire for selling a range of Nirvana t-shirts with prices stretching into thousands of pounds.The reason for the high prices is that these t-shirts are all “vintage”, rather than being brand new creations. And some are seemingly rare, particularly one featuring the artwork from Nirvana’s ‘Incesticide’ compilation, which is selling for over £3000.Still, while old band t-shirts can fetch high prices, some have suggested that these ones have seen their price tags inflated considerably above their market value, simply for the privilege of buying them from a YSL store.Oh sure, you could buy a brand new t-shirt with the same design on it for fifteen quid, but does it have that lived in look and feel? No.
