My wardrobe plan for Amsterdam was all about the layers. Jeans, plus a tank top, then a shirt, jumper and coat to be added or taken off when appropriate. This worked really well. The fabric I think is some kind of cotton blend that I bought in Birmingham with Ben last winter. The original plan was to make it into a dress but it's going to be worn a thousand times more as a shirt.
I used the men's shirt pattern that I drafted for uni last year and that I used for the white linen shirt I made a few months ago. This time I made the yoke a little longer and added seam allowance to the collar so it's much more in proportion. The only thing I'd change now is to widen the cuffs a bit.
I paid particular attention to the pattern matching across the centre front, side seams and sleeve seams. Miraculously the collar actually matches the yoke, with no particular planning. The only change I'd make at the cutting out stage would be to centre the check at the pleat on the back piece. It looks a little off here.
