Her dress glows when utilizing her Maiden abilities as well for some reason. She is a bad mamma jamma. Her dress glows when she's using Dust. That's the whole point of the writers telling us that Dust can be sewn into clothing and having Ironwood respond to Ruby mentioning her clothes glowing by talking about sewing Dust into clothes.

When her clothes are not glowing is more likely when she's using her Maiden powers.

It seems she has been refraining from using the Maiden powers, so they don't know that she is the one who stole part of Amber's powers.
