My FI's dad's wife (yes, technically his stepmom, but she didn't come into the picture till FI was in college, so not really a "mom") is wanting to wear an ivory/champagne colored dress to our wedding. My dress is ivory. She posted a picture of the dress to her facebook page to get the opinion of all her friends, who all said the dress was "fabulous", "stunning" and on and on and on.... They all also insisted she must get the dress in the ivory/champagne color. We don't have a bridal party and up to this point I've told her she could wear whatever color she'd like - she's been sending pics of dresses that are black, navy, bright blue - all fine. At no point did she send a pic of a dress that was ivory. Until two days ago, when she posted it on FB. I sent her a private message subtly stating that the dress was very similar in color to my dress and had she considered buying the dress in any of the other available colors? She bluntly said no, but would now have to reconsider her choice. She also posted to her FB account that "apparently the dress is too similar in color to the bride's dress and therefore this is no longer an option for me". She also posted pics of a few more dresses but everyone said their vote was still for the first dress... It bothers me that she would consider wearing a dress that is so similar in color to mine. I couldn't imagine doing that, especially if I were part of the family of the bride/groom (as opposed to a "regular" guest at the wedding...). Am I being unreasonable to want her to wear anything other than ivory??? Need the opinion of some other brides please!!! :-)
