Alteration
The bride was most worried about the MOH fitting into her dress. Or rather, being unable to fit in it. She wanted to replace her with someone who would be able to the dress as it was. The dress had been altered several times, and the bride refused to get it altered again.
Backup Dress
The story doesn’t end there. The MOH actually had a backup dress. However, the bride wouldn’t agree with her wearing it. She point-blank refused. Not only that, but the bride felt the need to clarify that she wasn’t ‘fat shaming’ the MOH.
