Odd seeing Tina Louise on an episode, (but not in a bad way)

The actual episode was pretty good, and she was fine in it.
But she didn't wear eye make up and looked kind of ... plain.
I kept watching and wondering if I would think she was attractive as in Real Life, and I'm sure she would be.
She was tall and slender but the clothes did not accentuate her figure, and she was a distressed female and wasn't supposed to be some WOW CHECK OUT THE GOOD LOOKING CHICK type.
The episode was more about Action rather than Character, and Tina was good enough in the role, but it just felt odd to be watching - TINA LOUISE - and wondering why I wasn't knocked out by how gorgeous she always seemed to be.
But she looked fine and I'm not one to insist women get all dolled up with make up, so it was just odd. But nice to see her in something other than Gilligan's Island.
