There is something a bit weird about this thread on Levi's. Now I am quite prepared to accept that there are a few things which may be cheaper 'due to' Brexit- even though on balance, it has led to prices going up hugely.
But Levi's has nothing to do with the EU, apart that denim was first made in France for dockers (de Nimes). They are originally from San Francisco, and are made in USA, Mexico, China, Vietnam and Bangladesh.
Hi Claremont
This was an EU issue, all around the protection of trademarks, which are referred to in the OP. In the late 90s, Tesco started a campaign against Levi (and other premium US brands) who would not sell directly to them as a discount retailer. Tesco began to buy up Levis from third-party wholesalers outside of the US/EU (on the so-called grey market). Levi Strauss took Tesco to court, claiming an infringement of their trademark, which included the right to choose who to sell too etc.
UK courts referred the case to the European court of justice - their judgment was in favor of Levi, but they referred the case back to the UK High Court for the final decision.
In 2002 the UK high court upheld Levi Strauss's right to decide how its brand is distributed in Britain and at what cost.
Of course nobody could foresee the impact that the internet would have on retailing in the subsequent years. People could shop all over Europe without having to pay duties (through the Free Market) while enjoying all of the protection that came with knowing that if they bought something that said it was Levi, there was a very good chance that it was. That of course, is what we decided as a country that we would rather live without.
I am personally pleased to live in a country that respects and preserves the protection given to both manufacturers and consumers from trademarks and other legislation. Of course it adds a cost, I happen to think it’s a cost worth paying. But of course that’s just my opinion.
