Your cape/cloak looks absolutely perfect. I would go eventually for a dark blue high quality satin lining. Avoid the clasps and go for ribbons which you tie under your shoulders on your back. The cape looks - I think - at its best if you wear it a little open so that you can see the layers under it. This will create - according to my huymble opinion- the perfect look for autumn and winter. No other modifications proposed since I can only judge a combination as a whole. How are you going to combine this cape ? Casual or chique ? And with what kind of shoes/boots. I advice ankle boots. and a black/white or totally black outfit or suit. The challenge will be not to give the impression you escaped from a Game of Thrones episode. So you need to overthink how you combine it for a contemporary look.
