From Ilsa, Harem Keeper of the Oil Sheiks.
I never seen the film myself, but I believe that they are duputies to Isla or guards, and not actaully slave themselves, being provided with military uniforms. Although, there are also scenes where they are stripped down to thongs, with body oil.
I prefer them in the thong and body oil than in a uniform, especially alongside the fully clothed Ilsa. Altough I like the idea that as free women, they can still be required to present themselves naked, I prefer the idea of female slaves, assigned dominant roles like guards or overseers, but are still subserviant and disciplined in their role as slaves and serve out their role as decoration. A chisled, but well disciplined female body is something worth celabrating, and should be kept on display.
I also love how their thongs are pulled tightly, inbetween their protruding asscheeks, a great way for them to be displayed, altough I do wish they were a bit thinner in the front.
