Using a variegated cream and grey yarn from a cone and knit together with a grey lace yarn to get closer gauge. Very pleased with the speckled stripey fabric but even more so with this lovely and precise pattern. I especially like the shirt tails and the picked up edging.

My only mods were to copy the decrease darts (found in the upper corners of border on the shirt tails) to each side of the neck border in correspondence with the shoulder seam and I used the smaller needle for the cream shoulder parts as the ribbing looked tidier and it made the shoulders a little narrower.
I will keep my eyes open for a special flecked yarn as I want to make this pattern again.
