(1st post, third picture down: I note he says it is a "gunmetal" tie, so I'm assuming blue / grey.)
For the daytime, I think you could swap a pale blue / white bengal or ladderstripe shirt and carry it off.
Another blue on navy from Charlie's Wardrobe. I'm not sure if it works as well as the last one I cross-posted, though the PS seems to do a lot to make it work.
I actually brought myself to the point of buying another navy blazer. I have been looking for something with white MOP buttons for when summer hits and I found a great deal. Just one peculiar thing about this jacket. As you can see it has white leather elbow patches. I don't know how I feel about this. I might have them removed. Thoughts?
