I also think Ruby's cloak is dust infused given it produces petals. I have absolutely no evidence but I don't think dust infused clothing has to glow. It would also go part of the way to explaining why she is so attached to it given weapons according to her are a part of the person who wields them. I think Ruby's rose petals are, at least partially, from her semblance. After all, Yang's flames are from her semblance. At one point in the Black Trailer, Blake trailed black splotches while using her semblance against the spider droid.

As for her different hood sizes, I think Ruby just owns different sets of red hooded capes, since they're sometimes even shaped differently, such as the one she wore with her alternate outfit.
