Size guide - How to choose your OL clothing

Would you like to order a shirt, t-shirt or pair of trousers from the official Olympique Lyonnais shop, but you're not sure what size to choose? This guide is here to help you. Whether it's for a match, training or lifestyle outfit, it's essential to know the right measurements to ensure optimum comfort.

How do you measure yourself?

To choose your size, take a flexible tape measure and follow these guidelines:

• Chest: measure around the widest part of your torso, passing under your armpits.
• Waist: measure around your natural waistline (the hollow between your ribs and your hips).
• Hip circumference: measure at the widest point of your hips.

Don't hesitate to ask for help if you need more precision.
