I think I’ve decided what to do: add some buttons to the mix!
I like this because it adds some punctuation to the middle and bottom and outlines the diagonal front slightly, without being obtrusive or heavy-handed. I will make this one into a mockup and take it to Sharon’s, to check the fit and see what she thinks of the design.
I like it! Is the collar deep enough to work as a hood? You probably don’t need a hood where you live though!
