Her cloak could also have the ability to choose a direction to accelerate in which she used to boost multiple times in the air. The ability to split into three seperate entities could be a combination of her cloak's ability and her semblance or just her ability to fully wield her cloak in general.

The only person that we know that has clothes that have dust woven into it is Cinder as her clothing lights up when she uses her glass attacks. She also has the ability to manipulate the form it takes like swords, bow and arrows, and projectiles.

Since Ruby's cloak emits rose petals on the cloak and not from her body i just thought they were similar in the way they activate. 1. I'm pretty sure the rose petals are still just a manifestation of Ruby's Aura, and her cloak isn't some kind of super special fabric or something. It's likely just Aura + artistic choice.

2. Cinder uses the Dust in her clothes for more than just attacks. Remember the liquid fiery attacks she used against Glynda in V1E1 (I say liquid because the shot that Glynda blocked splattered onto the ground) and the fact that her sleeve's designs glowed when she made the grass in front of her burst into flame while threatening Adam.

More likely, the Dust in her clothes isn't some kind of glass Dust or something. Rather, she's making glass by doing things like melting sand, which is exactly what she did in Beginning of the End. She kicked dirt into the air when she slid, then her sleeve's designs started glowing, and particles in the dirt melted and collected together into glass shards.

The swords, bow, and arrows she uses are obsidian, which is volcanic black glass, and apparently she, to some extent, has the ability to melt down and reform shattered obsidian, as seen with the arrow that struck Pyrrha's heel/ankle.
