Ok, so color-wise that is superb. Now we are starting to hit pay dirt.
I'll make 2 more small suggestions.
1. The herringbone pattern of the shirt is too close in scale with that of the jacket. A smaller herringbone would be better, but ideally Id probs not wear herringbone shirt and jacket together. This is a pretty fundamental point, and while the combo is real good, I would keep this in mind. Varying the scale across the board is something to always keep in mind.
2. The edge on the PS is almost the same color as the SC. I personally like a little matchiness in my PS, but more so with the tie or shirt, but right against the jacket it should not be the same color to the point they blend into each other. Considering this is just the edge of the PS, Id say while I think its a fair point, compared to the above its rather minute, and I bet some people dont mind it at all.
Great work, man!
Also, I took the liberty of fixing your pic by enlarging it so you can see what I mean, and because it looks so much better in large, and you deserve credit for that combo. Hope you are ok with that.
Thanks for enlarging the pic - I don't know how otherwise I would I totally understand what you mean about the two herringbones - I have another blue shirt that has tiny pin stripes that might be better.
