Sizing help needed!!!

[cyansakura.livejournal.com]

Hello everyone! :) I'm new here, so if I make any mistakes I apologise...

Anyhoo... I was thinking of getting the Ruins cathedral one piece, but I can't tell from the pictures whether it will go up any bigger than the estimated 82cm bust. I know it's probably a bit early to ask since this dress has only just come off of pre-order, but do any of you lovely people have this dress already, and have done some maximum measurements? If not, can anyone tell from the pictures if there is bust shirring anywhere?

Thanks!
