Like it says,[23/F] my stepmother [55/F] is wearing a pure white dress to my wedding later this month. She has been telling me the dress was a beige colour this entire time. But after seeing it in person the first time, it is pure white. 

She has already had it altered and with the wedding coming up there isn't much time to get another one. I find it a bit disrespectful - my fiancé [M/31] is pretty put off by the entire situation. I am also a little concerned as so why my father hasn't mentioned it to her that she is pretty much breaking the #1 rule of attending a wedding. Don't wear white. She never asked my permission and she seems to think it's normal. 

Now in the grand scheme of things it doesn't bother me all too much, more so my fiancé. Now should I say something or just ignore it and enjoy my day either way?
<bot>: My step mother is wearing a white dress to my upcoming wedding. Do I bite my tongue & ignore it or tell her to find something else in limited time? Curious to get a outside perspective !
