I'm posting here because I would like to buy this Baby dress (one of my dream dresses)

Finally I've found it but I wonder if it could fit me; my waist is about 76-78 cm, on Lolibrary I've seen the max waist is 76, but I bought in the past a Baby dress that didn't fit me, so I don't know if buy it or not.
Its name is Chocolate fascinate fairytale, hope someone already has this dress can help me... thank you very much!
