Am I being unreasonable to interfere with brides choice?

[Allequal]

I was shopping in an asian bridal outlet this week and saw a large group of white british ladies trying on Indian bridal outfits. I assumed they were all getting married but I got talking to one of them who explained to me that she is getting married to an Indian chap and that the other ladies were her family and bridesmaids. To which I responded "oh so they are all trying on the dresses to help you decide?" And she said "no they are picking outfits for themselves.

I was absolutely horrified and explained to her that in this shop the type of clothing is just for the bride, and that if her whole family are wearing bridal outfits the grooms family will be confused as to who the bride is, and it will detract from the day because there would be a lot of scandal and gossip during and after the event.
The bride was angry and basically told me off for interfering, said she was happy for her family to look beautiful on the day but I tried to explain to her that it isnt about beauty, it would be like seeing an Indian bride in an English shop and her whole family and bridesmaids are all planning on buying a white wedding gown to turn up to the church together. You know it would look ridiculous and would become a family joke eventually
But she basically said I was rude and the shopkeeper asked me to leave (naturally wanting to make a lot of sales).

Was i unreasonable for interfering? I just didn't want her big day to be spoiled.

It’s fine to tell the bride that the dresses are meant for the bride, but it is overstepping and quite rude to give opinions about how the groom or his family might feel. Your intention may be good, but it is better to simply state the fact that the dresses are usually for the bride and let her decide for herself. As the saying goes, not my circus, not my monkeys.

I think some people haven't read all of your replies about why the shop owner asked you to leave. I can see you were trying to help and it sounds like the bride was listening to you before he asked you to leave. It was also good of you to reply in English so they could hear your side of the exchange. There is only so mich you can do. Hopefully, by saying something she might've called her fiance for clarification.

I think it all depends on your delivery. You said you were horrified, so it may have come across as "telling her off" or trying to school her. Rather than your intention of trying to help someone out. But that's a tricky line to navigate and it sounds as though the shopkeeper getting involved escalated everything.

Really the bride should have gone shopping with someone who could guide her on the cultural norms - surely she must have some friends from Indian backgrounds or sister or cousins of the fiance. I guess it wasn't your "place" to tell her she was doing something wrong and may people don't like being told they are wrong.

Yeah you were being unreasonable, even if its bridal wear only they still will never outdo the bride especially when hair makeup jewellry etc is complete. I have never seen an Asian bride outdressed ever, even when other guests have worn their bridal outfits. Most likely the shopkeeper was charging them a premium but they largely make these prices up even to british asians who might not be able to speak the language. These shopkeepers also look at how your dressed and make an assumption. If the womans fiance or his family didnt warn her about this prior to her shopping trip they probably have the money to burn, especially if theyre happy to spend bridal prices on guests outfits lol.

I think you did the right thing, id want to know. Its weird that her family hasnt educated her on this or she hasnt researched so maybe they aren't exactly traditional. I definitely think it was the kind thing to do, being honest with her about it.
