I've been contemplating on buying myself one of these amazing long OPs by Moitié. Some of them have shirring and it would be perfect for my, ahem, bigger than average size. So I'm wondering if the Silent Moon long OP and the Alchemy Long Chiffon One Piece could stretch up to 114cm in the bust without being all stretched out and uncomfortable.
Here are pictures of the two dresses:


I'd really appreciate if someone could help with this!
