We have an amazing pastor at my parish.
If he thought this was necessary, of course I’d comply (although my white “blouse” would be a white t-shirt with some lace added to it, including a collar – don’t get all upset that a t-shirt doesn’t have a collar, I know it doesn’t).
Now, if the OP came to my parish and started suggesting that we have some sort of uniform for liturgical ministers, I’d be more than a little annoyed, to say the least.
From what I know of my pastor, he wouldn’t like that sort of interference either.
@duesenberg You seem to really, really, REALLY want this uniform to be implemented at your parish it seems. This is the second thread you’ve started on the subject after all.
Have you tried speaking with your pastor about it?
