Yesterday I discovered the woman who posed with the metal cups in this pic selling her metal cups online. She loves them but she had her breasts augmented so these B-cups no longer fit her:
I just paid her for them today and she's shipping them to me tomorrow. Yay! Once I get them I plan to buy spikes and screw the spikes into the holes on top exactly the way Maureen from Hands of Kali did in this picture (she also purchased these metal cups from the same artist):
Now if I can just find something leather like to sew the cups onto they can be part of my warrior princess costume for Norwescon (minus the spikes).
