I...guess that makes sense? I'd be more likely to throw on some old pajama shorts while painting than a skintight miniskirt but...eh. I guess she can stick to the middle of the walls? She won't be doing much bending over or step ladder climbing that's for sure XD
I'm glad there's a reason for dressing like Mini Shauna Sand but I still can't stand it. If she were my friend in real life words would be said.
This assumes she isn't also trying to be a bit of eye-candy for her girlfriend, which she might be doing just as part of smoothing things out between them. ("Yes, I know I'm not always as sensitive as I could or should be, and I'm sorry about that. But look--HAWT!") I'm not saying this would necessarily be a conscious decision, but I could see Penny's mind operating that way on a subconscious level.
