Let's state a point now, shall we?

All clothes in Remnant are fused or woven with Dust one way or another. The only difference here is percentage, and the way the method of creation Otherwise it'd be impossible for Hunters to take hits without getting their clothes shredded to pieces, which although makes excellent fan service does not exactly bode well wth RWBY.

Think them as your standard armor and equipment in games. That's Monty's explanation to stay stylish without having to adorn battle armor on our characters at all times. A simple yet elegant solution, in my opinion.

Cinder's clothing, particularly the runes that literally glowed with power, are woven completely 100% by Dust. We can assume that it's neither cheap nor easy right there to create clothes woven completely out of Dust. These are special battle clothing that has powerful offensive or defensive capabilities (+40% Fire attribute! Has a 2% chance of granting a instant boost of +100% Fire damage! IT'S SUPER EFFECTIVE FOR DESTRUCTION!).

Finally, one more thing that must be mentioned is that Ruby's Crimson Cloak is likely woven out of Dust, and has either a very high or 100% Dust concentration in it. It seems to have terrific defensive or regenerative capabilities, because it showed no signs of damage at all after getting pierced by a Nevermore's feather. It almost definitely has other hidden properties that may or may not be revealed this Volume. A final and extremely powerful gift by her mother, Summer Rose.
