This is a really cool manga! That being said, there is a major problem with the sizing in chapter 1!
There's a problem with the EU bra sizing system, where the band's are actually made 10cm too big, and you end up with a smaller cup size than you should. This matches the +4 practice that is common at EVERY SONGLE RETAIL LINGERIE STORE WITHOUT EXCEPTION where, in UK or US sizes, they will tell you a band size that is 4 sizes too high, and a cup size that is (at least) 2 sizes too low.
In reality, Umemiya Ran (our main character) should be a 55D (or a 26D in the US or UK systems) instead of the 65A/30A she was told.
You might notice that her underbust measured 65.5cm, which is equal to about 26.1 inches. The UK system is the more popular with with people in the ABTF (A Bra That Fits) community because the proper band size actually matches your underbust measurement.
The rest of their advice is still 100% true, though, including the actual method for measurement, just not the final size!
If you want to know more about this stuff, I very highly recommend looking up A Bra That Fits! There's a wonderful Reddit community and Discord with people who know way more than I do!
