Jewelry Jelly measurements?

So, I'm thinking of buying the regular Angelic Pretty Jewelry Jelly JSK, but I'm not sure of the actual measurements. A lot of websites claim it has a 68cm waist and an 88cm bust, but I've heard since it's one of the ones with full back shirring, that it can stretch a whole lot more than this, however I haven't been able to find any documentation of how big it'll go. I was just wondering if anyone knew how big it could actually go? I'm hoping I'm below the max. measurements (98cm bust, 84cm waist for me), but I'd like to know for sure before actually buying the dress. Thanks!
