See, I remember watching Superman: The Animated Series where Lois, to me, came off as being this very stylish and glamorous woman in the same kind of natural way you see in Selina, albeit maybe not as in-your-face about it or a tad more casual, so that kind of informs my take and what I usually expect from Lois.
That's the same feel I got from Teri Hatcher as well, and what I felt Erica Durance eventually developed into on Smallville.
