About this guide

I started it because I kept buying the wrong thing and could not find a plain explanation anywhere.

Intima Sovet started in the autumn of 2021 as a single document: a personal spreadsheet of bra styles, their Japanese size equivalents, and notes on which brands sized consistently. Mia Tanaka had spent years buying the wrong size in the wrong style, returning things, and starting over. The spreadsheet grew. Friends asked for copies. By winter 2021 it had become a proper reference, and by the following spring it was a website.
