This is a stock, adjustable under-bust corset with Molle webbing holding a spare 33rd magazine for Sub2000 carbine. The small pouch also works for Uzi magazines. Other accessories can be added as needed.
I'd like to see the first picture with a darker background. I understand that you probably want her to fade into the background a bit, but the lascivious side of me wants to see her dynamite figure better. ;)
