"I think, Papa," said Mrs. Popper, "that you had better take Captain Cook outside for a little exercise. Good gracious, but you're all dressed up. Why, you look almost like a penguin yourself."
Mr. Popper had smoothed down his hair and shaved off his whiskers. Never again would Mrs. Popper have to reproach him for looking as wild as a lion. He had put on a white shirt with a white tie and white flannel trousers, and a pair of bright tan, oxblood shoes. He had got out of the cedar chest his old black evening tailcoat, that he had been married in, and brushed it carefully, and put it on, too.
He did indeed look a little like a penguin. He turned and strutted like one now, for Mrs. Popper.

One of my favourite descriptions. It's pretty funny to imagine. :-)
