Fletch said:It could work, but you run the risk of looking a little stale. With the right tie, though, you can avoid that.
I've mocked up some ideas for vermifuge to kick around.
Here are foulard, paisley, and art deco ties with ecru, green, and blue shirts.
The foulard/ecru is businesslike to me. The green/paisley has a British feel. The blue/Deco is 1940s in colors as well as style.
I think your first choice is best. you have a good eye!
