Hahaha - Cube might have, but I'd like to think that Ralen's original intention was to point out that all of them except the leftmost one are wearing white thighhighs and a maid hat, and don't have glasses, whereas the leftmost one is wearing black thighhighs and a garter, no hat, and glasses. At least, that's what one thing I noticed not being like the others.
Although the arm does look a bit like a penis on the one on the left, 0xCCBA696 is correct. The one on the left also has neither gloves nor ribbons in her hair.
