Una, are you sure you could not wear Janet's jacket? That jacket also looked good on Diana, if I recall correctly. Or maybe I am thinking of another one.
I do hear what you are saying, though. It's tough to find stuff that reads that dramatic.
Gryffin, I think for me it is slightly proportionately short legs....but also, just not being used to the silhouette on myself and/ or not being able to style it all that well.
Una -- you're already a pro at it from tunics/ skinnies. (This is a look that doesn't seem to suit me all that well -- it's to do with my thigh shape, I suspect. And if makes me sad because I love it!).
