East Wind Chair Covers

Hello! I never really formally introduced myself around here but my name's Amanda and I'm getting married July 2 at the East Wind Estate. (5 months to go and so much to do ahhhh!!!)

I was wondering if anyone had ever used chair covers for the East Wind chairs, I'm told they aren't the same measurements as other banquet chairs. I found chair covers that I love but they are for purchase only and before I buy 150+ of them I wanted to be positive they would fit. Does anyone know the measurements of the chairs or know the measurements of the chair cover they used or have a recommendation for where they got their chair covers from???

Thanks so much!!
