I found a wonderful description of Philippa of Hainault. She and Edward III met while children:
king and queen's first meeting:
"He spied on the unwitting sisters, and pounced on the youngest of them, Philippa by name', at the time eight years old and nearest in age to Edward, who was nearly seven years. He had then subjected her to a minute and terrifying scrutiny. Apart from some criticism of her remaining baby teeth (they were 'not so white', he had found little fault with her solid physiognomy. Her hair betwixt blue-black and brown and not uncomely', her forehead large; her eyes blackish brown and deep, her nose though 'somewhat broad at the tip and also flattened', was 'yet no snub-nose'; her mouth was wide and generous, her ears and chin were 'comely enough', her mouth was wide and generous, she was of middle height for her age, well taught, and of 'fair carriage'.
'Her neck, shoulders, and all her body and lower limbs are reasonably well shapen; all her limbs are well set and unmaimed; and nought is amiss so far as a man may see. Moreover, she is brown of skin all over, and much like her father; and in all things she is pleasant enough to look at it seems to us.
