As controversial as it is, Kubochan isn't the first one who had their three sizes revealed. If you check Maiyan's japanese wikipedia page you can find her three sizes as well. The source was FLASH Special, released in 2011. I don't know about other members though (especially who double as model). This is the scan of the entire page Bonus, from Sailor Moon
The measurement of Bust - Waist - Hip. It's common for fashion/gravure model, but as @MasToppu said, usually for Nogizaka member this data isn't public.

Nogizaka Cinemas Ep 09 preview cut from the digest video (geoblocked on Youtube) https://streamable.com/hzg4a Looks eerie
Kubo Shiori is appointed as 2020 image character of Eagle Girl, which is Japanese baseball team Tohoku Rakuten Golden Eagles' cheer group. if the video does not show watch the video here
Elaborating on this, Eagles Girl is not actually the cheer group, as that would be Tohoku Golden Angels and Kubochan was a junior member before she joined Nogizaka. Eagles Girl is more like the name of Golden Eagles fanclub for female fans. As for the image character itself, the appointed ones are usually celebrity/idol who came from Miyagi. For 2018 it was Ishida Ayumi (Morning Musume) and Sasaki Rikako (ANGERME), and for 2019 it was Ishimori Nijika and Moriya Akane (Keyakizaka46). If I am not mistaken, this year is the first time the image character isn't a pair, just Kubochan solo. Kubochan is scheduled to appear at the opening ceremony of the match versus Yokohama DeNA Baystars on May 31st (first pitch? I hope so. IIRC the last time a Nogizaka member threw a ceremonial first pitch for Golden Eagles it was Maiyan in 2013).

Guess there are 5 girls lined up for Kubochan's future LINE LIVE. One I'm very excited to see is my favorite pick in the just concluded Sakamichi draft Sato Rika who is a Kubo-oshi. Can't wait for all of them to finally join the group. This day (at least for me) is a great day.
