Rubberwolf, I believe you are correct in wanting to give your readers a least a basic idea of what your characters look like, however it's important to remember that, here on line, you're writing for www. I live in Australia--we're in metric measurements, so a 24 " waist isn't going to mean much to most Aussies. Also, male readers who aren't as savvy about women's bras as you, aren't going to be clear on how big 34DD tits are. This is the reason people who know a whole lot more about writing than me always say: Avoid using exactly measurements.
