Jeans... 140 years old and still so cool!

Every day, you get up in the morning and put on your jeans. On 20 May, it's the official birthday of the world's favourite trousers. But how much do you know about them?

Mini pocket
This used to be called a watch pocket - people put their watches here to keep them safe. It has got smaller with time, and is now called the coin pocket.

The rivets
In 1872, a tailor called Jacob Davis used copper rivets to reinforce the pockets of Levi's jeans. He and Levi Strauss became business partners. They patented their method for making jeans on 20 May 1873. The next year, "501 jeans" went on sale.

The belt loops
Levi's first belt loops on their 501 jeans in 1922. Before then, people wore braces: jeans had suspender buttons to attach the braces. Until 1960, jeans were called "waist overalls".

The denim
Levi Strauss imported cloth from France called serge de Nîmes to make his jeans. In the USA, it was easier to call it "denim" (de Nîmes). Today "denims" is another word for "jeans". Denim fades with time but it looks really cool!

Zip or buttons
The first pair of jeans had a button-fly. In 1954, Levi's made its first pair of jeans with a zip.

Skinny jeans
Punks wore skinny jeans in the 1970s. And British top model Kate Moss made them popular again in 2002. Today, people all around the world wear skinny jeans!

The stitching
On jeans is often in orange thread. This tipe of thread is very strong. The colour matches the copper rivets.
