Levi's jeans have become a staple in everyday fashion for many consumers. And if you have a pair sitting in your closet, you may want to check the tag.

People have been urged to check their wardrobes as vintage pairs of blue Levi's jeans go up for sale for £8,000 - but there's a few things you need to watch out for

More than 1.25 billion pairs of Levi's blue jeans are sold around the globe each year - but not every pair has the same value. American clothing firm Levi Strauss & Co was founded in May 1853 by German-Jewish immigrant Levi Straus, who made most of his sales through the working people of the western US.

Levi’s owners are checking the tags of their jeans after it was revealed that some of the company’s vintage garments are worth a whopping $33,000. Jeans made by the brand between 1949 and 1954 are selling for astronomical amounts online, and there’s an easy way to date the denim.
