In this weather, some of my favourite things to wear are sheer shirts or similar, over a sleeveless top. I think this would look fabulous, as you could wear almost any colour camisole / shell top underneath, or even a sleeveless dress.
As I have posted about the Ready to Sew kimono jacket many times, I'll us this as an example: https://sewingpatterns.com/collections/park-bench/products/park-bench-pbp14
I have made this many times, and as the 'facing' is actually the front band, it really works well. I wore one made in a bronze coloured organza, over an ivory dress, to a wedding. I really am awful at photos, I seem to have deleted all the ones of that wedding (?how?!)
I used french seams for that one, but have later used an overlocker. I also reduced the width of the front band.
