Edwardian Adventuress: The Shirtwaist Plan

So I am planning on putting together an Edwardian adventuress ensemble, the sort of outfit a lady might wear while sketching Egyptian ruins while on a Nile cruise in 1907. I already have an Edwardian corset so I am planning on making a white cotton shirtwaist, a kakhi or brown walking length skirt, and a brown belt/sash. I'll also need a new walking length petticoat but that is more boring. I will be drafting the patterns for these items myself, and I can't wait to get started this upcoming weekend!

The first piece I want to make is the shirtwaist. I found the illustration below on Pinterest which should help me with drafting the pattern, but they seem pretty straightforward over all. Hopefully they will have a nice lightweight cotton at my usual fabric haunt this weekend. I may end up also needing to make a simple corset cover or camisole to wear underneath too depending on how sheer everything turns out.

I really like this example with the lace or net fabric as a yoke and the standing collar. I'm pretty sure I will try and draft my own shirtwaist with a similar style line, hopefully I can find a suitable cotton lace/eyelet fabric or I'll perhaps have to make the yoke fancy with pin-tucks! 

Have any of you made an Edwardian shirtwaist before? If so, do you have any tips for me before I dive in?
