It's entirely possible Ruby's cloak is infused with dust,  considering it also "scattered petals" at the beginning of her trailer.

But I believe you're thinking of the short-range teleport near the START of the Red Trailer, when the Beowolves first try to pounce on her. She even disappears with accompanying rose petals!

Also, Weiss used pretty much the same gesture when she used her "air jump" as she did in the white trailer: finger to Myrtenaster, then towards her feet. This would suggest to me that Dust (for the most part) needs a focus of some sort - a weapon or piece of clothing, for instance.

don't mind me, just rambling...
