Gianni, in my view, this would have been perfect if it had been a grey flannel suit (like the jacket). The yellow trousers, while they are beautiful in themselves and would work in a summer outfit or with a different colour coat, are just too reminscent of Ronald McDonald with the (also lovely) red coat.
Thank you for your kind comment ... you're right on the jacket. But the fabric of the jacket is very vintage. And there was even more to make the pants .... but then I really like the color =) ... but usually that I match the jacket photo of a dark gray flannel trousers, always vintage. Then I will show you.
