Jeans have become a key item because they so easy to work with its one of these items that can be dressed up or down really easily. In terms of fits, we've now got less emphasis on the skinny and slim-fit jeans that have dominated the last few seasons so feel free to eat pies and drink full-fat Coke again.
There are plenty of fits to choose from loose-fits are great for a very casual look, especially teamed with leather jackets and a classic white tee. If you want to smarten things up a little, you can try boots instead of trainers, and to look both effortless and stylish, keep the colours toned down and simple.
