Lapel width is considered "wide." Ask AL about the fabric.

Not sure about the gret trousers if I'm honest, but jacket and shirt are cool. I'd probably go with white/cream trousers for that jacket shirt combo, especially if you have brown shoes/belt. I'd also consider shortening the jacket length by 2", I don't like to see jackets hang below the groin V, but perhaps it's just the way you are stood. The sleeve length looks ok.
