Reddit users were solidly on the OP’s side.
One wrote: “NTA. If it were ‘just a dress’ like your brother says, your future SIL wouldn’t make such a big deal out of your refusal. This is your dress to wear some day – or not. But it is your special connection. Not hers.”
Another agreed, commenting: “Nta. I would hide the dress at a trusted friends house until after the wedding. The rest of the family can kick rocks, this isn’t their dress so they have no say on the matter.”
Meanwhile, someone else jokingly suggested, “If it’s “just a dress” and your brother wants a connection to your mom there, perhaps you should wear it to their wedding instead…😉.”
