Cinder does have fire dust in her dress; she uses it in the fight against Amber to glass the dirt she kicks up and send it at her. I also assume that when she gathered the fire from her arms in Ep1 against Ruby and Glynda she was gathering the Dust from her dress, and the explosions she made against Amber before she got the Maiden powers were made with Dust infused in her arrows, or at least stored there. And the Dust sewn into her stealth suit lights ups whenever she is creating something, like her swords or bow.

In the first two instances, the decorative stitching on her sleeves light up. In the last instance, I believe the vortex appears where her arrows are sitting in the ground around Amber.
