AITA for asking my brother and his wife for a refund after they bought a wedding dress for their daughter without my wife's consent?

My brother's wife is a bride planner. She asked my wife to trust her with the wedding dress budget and everything else wedding so that she can plan the whole wedding for our daughter ahead of time, so that we don't have to worry about anything. My wife trusted her.<br><br>My brother and his wife saw some expensive dresses online. They told my wife that they ordered the dresses and that it was their right as parents to choose the dress for their daughter. My wife argued that it was our daughter's wedding and that she should have a say in what she wants to wear, but they over-ruled her.<br><br>My wife talked to our daughter about the dress issue. Our daughter loves fashion and is very particular about what she wears. She hates the dresses they chose for her and asked them about the money. They said that they'll pay for the dresses no matter what. My wife's daughter asked them to refund the money so that they can find the dress she wants to wear.<br><br>My brother and his wife refuse to refund the money. They told my wife that she chose to trust them with the planning of the wedding so now she has to accept that they will pay for the dress no matter what. My wife got mad and said that she doesn't want them to spend money on the dress of her choice.<br><br>I talked to my brother and asked him to refund the money. He said no. I said that I'll pay for the dress that our daughter wants to wear and for her choice of wedding attire. He said that he'll pay for it and no one will take the dress unless he decides to. Both families are involved in the planning so I don't know what to do.
