but the maggie and sottero a3151lu Wedding dress was HUGE

I will be a bride and I bought this for my mom for my brother's wedding. My mom had tried on all the different maggie and sottero a3442 Wedding dresses in the stores first to make sure to get the right size. mom is petite so she ordered at 4petite because it fit her perfectly for the mon cheri dress. When the maggie and sottero a3311lu Wedding dress arrived, the label said it was size 4P ..but the maggie and sottero a3151lu Wedding dress was HUGE...way bigger than size 4, not even a size 6, it was like a size 8. we spent a bit of money to get it altered,I think I must buy my wedding dress from china
