The mother of the groom is wearing a white dress.

I would have your FS speak to her. She should be pretty understanding that the bride doesn't want her to wear white to her wedding.

I would have someone else ask her why she's wearing white. If you have a good relationship, its likely she didn't mean to hurt your feelings. In the end, I wouldnt be too worried about it- everyone knows you're clearly the bride.

One of my good friends- her MIL almost wore white to her wedding because she wears white every sunday to remember the passing of her other son. Someone mentioned to her it may not be appropriate so she wore silver or something similar instead.

Personally, as long as she is not wearing a white ball gown, I don’t understand why this comes up as an issue. No one will mistake your FMIL as the bride or a bridesmaid. Maybe she felt best in that dress and color. I doubt she had any purposeful intentions with this.

I absolutely hate people who do this but honestly your FMIL will look like the biggest jerk on the planet... there's no way no one would be mistaken to wear white at a wedding. Let her do it and everyone will give her stares. I still think it is incredibly rude and I would want to say something but her deciding to wear white says a thousand words.

I would ask your FS to talk to her-- if she changes it great! if not she'll look like the rude idiot attending.

Definitely have your FS talk to her. Although I can’t say I understand anyone’s thoughts when choosing a dress and choosing white. Isn’t that basic wedding etiquette?

This is so bizarre to me. Why choose white?! Could it be some cultural thing? I think it’s okay to talk to her, or have FH talk to her...maybe if FH does he can play dumb a little , like “oh, that’s interesting, I thought only the bride wears white?!” which might pique her concern? I’d definitely address it while there’s still time to switch the color . I’m sure she didn’t mean to
offend, so I think a simple conversation will be effective. Like a simple “it’s a lovely dress! oh? It’s white? I was kind of hoping I’d be the only one! Were there any other colors you liked?”

Any idea why she chose white? Is it her favorite color? Cultural? Are you wearing a colored gown so she figured white was allowed? Just trying to figure out what her possible reasoning behind this could be.

If you have a good relationship with your FMIL then I think you can bring it up with her directly. The next time you see her I'd say, "Hey, X, something has been on my mind ever since you showed me your dress for our wedding. It is a gorgeous dress but, honestly I'm a bit disappointed since I was hoping I'd be the only one in white that day. I'm not sure if it's possible but, would you be willing to exchange it for another color?"

If she is as nice a person as you say she is then she will be mortified and go out of her way to exchange it for something else. If she doesn't and wears it anyway then you learn a very valuable lesson about her and she will look like a jackass to all the other guests.

If you have a civil but, not close relationship with her then I'd have your FS mention something to her and hope for the best.

I would have your FH talk to her, just because its his mother, and it doesnt have to be a mean talk but just let her know we can go and find you another dress and we would be happy to help you pay for it if need be or something like that idk! Im sure she meant well by it

Why does anyone, especially a mother of the bride/groom, think it’s ok to ever wear a white dress to a wedding unless the bride asked them to? If I ever saw this at a wedding, I would be embarrassed for that mother. I would have your FH talk to her. Maybe he can tell her that he was hoping his bride would be the only one in a white dress on your wedding day. Also I feel like a white dress next to a white dress would really stand out in your photos and be weird, and I wouldn’t want that.
I would be really disappointed and sad if my FMIL did this to me. I would personally see it as spiteful and think she did it on purpose (for my FMIL, who is a very spiteful person, just FYI. She literally threatened to wear a white dress to her nephews wedding because the bride pissed her off once 😑🤦🏻‍♀️).

I would say something! If she's truly a sweet woman you don't want the other guests whispering about her all throughout the wedding. And you can use that as an excuse say something along the lines of "that dress is beautiful on you but could you maybe wear another color, my family is strong believers in only the bride should wear white, so I really don't want you receiving any negative attention at the wedding"

I can't imagine she didn't do that on purpose, for negative reasons. No one buys a white dress to wear to a wedding, especially one that looks like a bridal or wedding party gown, from a wedding store, on accident. I'd talk to her or have your fiance.

No one will think she is the bride. Don't worry about this- it really is not a big deal.
