Not a fan of the Duke's outfit there (not am I generally a fan of what he wears). I like how Grant dresses, but I don't recall either he nor Astaire ever wearing blue or blue grounded shirts.
Regardless, citing historical figures is, and has always been, a silly way to make an argument. XX does it, therefore it's ok.
The question is: do you mind large expanses of the same color in different hues? And if so, why?
The blue-blue-blue is extreme, but a blue shirt with a blue jacket, I think, is pretty standard.
In general, I think variety in hue and vibrance is more important than variety in the colors themselves, particularly with two items (as opposed to three or four).
That being said, I'm a big fan of brown patterned shirts with blue jackets. And regardless, it's nice good for thought.
Agree with this. I also like blue-on-blue, especially blue shirts and blue suits. I think there's a congruousness in the fit you posted today that works.
Where you lost me was with brown patterned shirts. My imagination rebels trying to picture that.
