Why did the cape fall out of fashion? It strikes me as an eminently practical garment suitable for both rain and wind as well as having a certain casual air to it. You can easily put them on and take them off; they shield you from the element, and have a cosy aspect about them. I suppose it's a somewhat theatrical garment, but trench coats, Chesterfields and the like have survived. Perhaps SoCal2NYC can post a picture of his own Raf Simons cape. However, there are some unfortunate imagery associated with the cape--notably, obese Renaissance Fair participants and disreputable people of that ilk; but then one wouldn't expect anything remotely elegant from those types so a good cape is still safe to wear.
