Question about AatP Vampire Requiem

Hi! I tried to search for an answer for hours but couldn't find anything (maybe I wasn't using right words...) so I decided to ask here! I love Vampire Requiem Corset JSK and I found the measurements in Hellolace. The first version and reserve version have different measurements. So I wanted to ask if they really are made different even though it is ''the same dress''? And also are the measurements in both dresses correct in Hellolace? Sometimes they are a little off. If somebody of you lovelies have the dress (any version), it would be awesome if you could measure the max measurements of the dress yourself : ) Bust and waist. Thank you very much! : )
