Beautiful but big for me

Hello, everyone should be given its size and that the vest chooses as me for example, I am rather athletic 1.80m (71kg), so I took a XXL vest following the many comments out there this vest is great to length in the closing level ... it comes down to me and far too many folds in the stomach and chest due to greatness. So I'll send it and would take another against because of it's true that it is beautiful, BUT, I do not know what size to take, the XL or L .... ??
