Maybe. You know how when spray paint gets old & clogged it can make drop instead of a fine spray? that might work to your advantage here.
Another, more tedious but would be awesome looking, effect is to go get the flocking powder from the scrap book section of your local crafts store, mix it with the iridescent super fine glitter (same section) and figure a way to make it stick to the hoodie. That would really look like frost.
