A little guide to what the EAH characters were supposed to look like according to the books,since the show has changed the appearance of many:
Apple: Is described as curvy in the bosom-hip area, and in general she has soft features (I remember that her lips were especially described as full). Darling used the term "plump", so she is indeed curvy. She needs glasses, but uses contact lenses. She shorter than Raven. Vox populi the fairest of princesses
Raven: She's taller than Apple,but still in the avarage height. It's not explicitly stated, but given that she compares herself to Apple in her chapters,It's safe to say that she's very thin and relatively flat-chested. She looks a lot like her mother, who was very beautifull
Maddie: The shortest girl in the school. Not just short, really petite. She gets her hair from her father, who is completely mint green in the books, unlike in the show where he is blonde.
Briar: Apple confirms that she's one of the tallest girls, and when she wears heels, she's actually the tallest. We also know the actual style of her, since she often expresses her passion for heavy jewelry, leather skirts and boots, sequined tops.
The Charmings: The siblings DO INDEED look alike in the books. Daring and Darling have the same WHITE blonde. Daring is "only" athletic, while Darling is described as muscular due to her training. Dexter is described as lanky. He and Darling are probably the same height because she uses his armor.
Hunter: He is described as very similar to his mother,with tall and broad-shoulders BUT not to the machismo levels of his father, who is "similar to his wife, but taller and broader". Fun Fact: in the books, Cupid is attracted to him and not Dexter.
Sparrow: While the show kinda painted him ugly, In the books he is very cute. Raven admits that despite her efforts she is still attracted to him (physically). He's not a redhead! In the book he has brown hair and dark green eyes. They are from his dad since his paternal aunt has the same colors. However, on a physical level they don't look very similar,so he's taken after Marian more than Robin
Cedar: She's visibly made of wood, but unlike the series, so is her face. When she became human her face "is soft and has taken on color"
Cerise: She's very tall and muscular. She has the typical muscles of a sprinter. Raven is really charmed by her
