When I initially met with one of my bridesmaids last month (a relative of my future hubby whom I like quite a bit) I said I wasn't too particular about what shoes my bridesmaids wore. She exclaimed that the shoe color HAD to match and came up with a color that all the bridesmaids should wear. She seemed pretty adamant about it and insisted this was very important so I said OK and immediately texted all the other bridesmaids to tell them we were going with the color suggested by the relative.
Fast forward to now, she texts me a photo of the shoes she got for the occasion and they are NOT in the color she insisted upon. All the other bridesmaids have since gotten their shoes in the color. I don't really care, but I think this relative will care quite a bit if her shoes don't match everyone elses. I don't want her to feel embarrassed or upset her at all.
How do I ask her politely or let her know that we are going with a different shoe color?
