This MAY be a bug, maybe an oversight, or maybe it's intentional, not sure. When trying to see what Alissa is good at (not much), I was wearing the waitress top. During Alissa's beyond horrid attempt at working at Roxie's Diner, Lust didn't have the waitress top on (meaning she was only wearing a pair of pink panties, did I forget to put the shorts on?) so either Alissa's borrowed Lust's clothing for the attempt, or it's a bug...
Given how much of a psychopath Arlene is, I'm wondering if you have some plan for her and one of the other ladies (Linda would be likely, given how some of the Science Lab stuff is apparently not-quite-legal, and I imagine a confrontation between Arlene and Linda would be quite interesting!)
