I think the sexiest thing Lois ever wore was Clark's shirt. I remember I just LOVED that scene. It just cemented their relationship for me. I don't know why, they just look so COMFORTABLE with each other when she comes to him in that shirt and sits on his lap, I just scream "I want my show back! Why was it cancelled, d*****! Look at them! THAT is the definition of a married couple!"
Now, I tend to remember outfits I HATED Lois in more than the ones I loved and I would seriously love an explanation of her entire 3rd season look, but that's not the question here so...I also liked her costumes from Soulmates, the robe she wore in that eppy when Superman says she and clark are lucky to have each other, her around the fire outfit in "Ordinary People" and though it was a little extravagant, her dress in the eppy in which Superman shows her was real dancing is. Oh! And her outfit in "Season's Greedings"! I had a thing about wearing ties after that.
