The shapes, the colour patterns and even the battle damage are all very reminiscent of Qrow's look in Volume 3. All I'm saying is this: In RWBY, costumes tend to matter in some way or another; everything tends to have a subtext in some form. There is going to be a significance in how Ruby's look has changed beyond the obvious. Ruby and Yang are half-sisters confirmed.

Unless Qrow did his sister to some how create Yang, your previously mentioned theory is impossible. Didn't mean to be rude, I honestly didn't. But that above mentioned fact was given by Monty himself.
