I thought "The Bra Zone" was a quick and easy read, $1.99 on amazon kindle.
Mostly filled with the basics that I already knew, and tbh most of the info can be found on other sources (blogs, youtube videos, abtf forum, here...) The most interesting is to hear her story re: anything above a D-cup back in the day automatically put people into "granny" styles, which I've heard before. Wow, how far the industry has come !!
Plus, I discovered her blog https://www.thebreastlife.com/ Quite interesting and has some good info as well.
