Polo Ralph Lauren Jeans

Start by measuring yourself. Jeans sizes have two measurements, measured in inches: waist size and length. Size 28/32, for example, has a 28-inch waist and a length of 32.

To determine the correct length, measure the inside of your leg. We recommend that you measure a pair of trousers that you know fit well – this is easier than measuring your body. To get the waist measurement, measure yourself as high up on the waist as the jeans should fit.

If you are between two sizes, you should choose the smaller size, as this will allow your jeans to fit well. They stretch, so if they are a little loose at the waist already, they risk becoming too big. As a rule of thumb, they are not the right size until you have worn them ten to twenty times. Many jeans can also shrink in length when you wash them – usually up to a couple of centimetres, so don't buy jeans that are too short.
