I think that both corsets could be used in fantasy costumes. I can imagine the turquoise corset being worn by a mage or other caster, and the green underbust corset worn by a hunter-ranger or perhaps a rogue.
I'm thinking about making another brocade corset with white cotton coutil panels rather than the imitation leather. In addition to steampunk and Neo-Victorian, I think that it would be great for frost mages or "good" casters such as priests.
Both corsets and the backpack are available at my Etsy store. I just opened and am adding new designs daily, so check back if you like what you see!
