Marc Jacobs believes modern grunge is "style without substance''.
In 1992 the designer famously showed a grunge-inspired line for his then-label Perry Ellis. Although fashion critics loved the pieces, the collection didn't sell and the following year Jacobs was dismissed from the company.
The plaid shirts and clumpy boots are now seen as the embodiment of that aesthetic. During the recent show season grunge made a comeback, with Saint Laurent in particular showing checked tops, large overcoats and flimsy dresses.
Jacobs believes some of the message of the original 90s look has been lost for young people today.
"Now it's just style without substance,'' he says.
