@PotomacBobI often include height as a number, but oh my god, I hate getting a block of text that tells me the proportions of a girl.
In Shelter In Place On Haunted Hill, I describe Nadine as 3cm taller than Heath. The other three girls are shorter.
In Flying Fox and Warhound, I point out Amy's 185cm tall, but she's chained to a desk and trying to reach out with her leg to reach a cabinet:
Usually, she found a hundred eighty-five centimeters was too much for a woman. Right now, Amy could've used another fifteen.
This also drops in that a girl 185cm is a bit self-conscious about her height. Works for me.
That said, direct numbers are much worse than context clues:
She was short, he was tall, they could only kiss so long before need, desire, and geometry broke them apart.
The other point, just writing out what size bra she wears? Uh. Better to just say, she's got big tits. Or small tits. Hand size. There's always the classic produce comparisons: Peaches, cantaloupes, watermelons, pineapples, kelp, state-fair winning pumpkins.
I dislike straight numbers. I dislike just dropping a character sheet as a paragraph early on. But I do get the point of getting the character description over and done with so you can just stick to names. Because, if, down the road, someone doesn't remember all of the details from chapter one and forms a different image in their mind, redescribing the character can break immersion.
I was reading A Strange Geek's Haven series and when he goes for chapters without describing Cassie, I get a blonde in my head. Then he describes her as a brunette, ruins my immersion for a dozen paragraphs, and then I'm thinking blonde all over again.
If you're writing a porn story, and the character's part of the sex, your audience is gonna imagine them as hot. Takes a lot of the work out of your hands.
