WHAT SIZE ?

The Marseille 21 fits normally. However, if you are usually between two sizes, we advise you to take the larger one.

The Origins and Line 90 size a little bit large. We advise you to take your usual size, and if you are between two sizes, we advise you to take the smallest one. 

Example: if you usually wear a 42 or 43, choose 43.
Another example: if you usually wear a 38, take a 38 (logical :))
