Should the bride pay? Am I wrong for being frustrated?

My brother is getting married in June of next year so my sister in law is already preparing. Today she wanted to go dress shopping. I wasn’t able to go but my sister did go. We were suppose to look at dresses and did not plan on buying anything today. My soon to be sister in law instead choose everyone’s dress to try on and the place mind you this was only to look so no budget was discussed and then went on to tell everyone they had to buy the dresses today that she picked. She said everyone had to pay out of their own pocket. $240 a bridesmaid dress plus shoes she picks on top of that. Mind you her and my brother have plenty of money for this wedding and put part of it to a new roof and wanted my parents to pay for part of the wedding because her parents were. Am I wrong for thinking she should pay if she’s picking the place to buy the dress, the dress and everything.
