These similes are poor ones, I'm afraid, but I find it difficult to put my thoughts exactly into words.
These particular soldiers were most unhappy looking, all except the half dozen Turcos among the Frenchmen.

They spraddled their baggy white legs and grinned comfortably, baring fine double rows of ivory in their brown faces.

The others mainly were droopy figures of misery and shame.

By reason of their hair, which they wore long and which now hung down in their eyes, and by reason also of their ridiculous loose red trousers and their long-tailed awkward blue coats, the Frenchmen showed themselves especially unkempt and frowzy-looking.

Almost to a man they were dark, lean, slouchy fellows; they were from the south of France, we judged.
