People who know a lot more about these things than I do say never use exact measurements, use descriptions instead. To my other half, who’s never had to buy a bra, 36D are just numbers and a letter, but he sure knows what big round tits are. Apart from being more interesting and colourful, it’s also important to remember that while Americans are in imperial measurements, most other countries are metric.

I believe any author of fiction who uses exact measurements is, generally, doing themselves a disservice.
