Attending son’s wedding in August this year as MOG. I wanted to avoid a clash with the MOB with outfits so asked what she had planned. She was going with pink mix to coordinate with bridesmaids. Based on this I spent a small fortune on a navy blue / lilac outfit and accessories. Five months on she changed her mind and bought an outfit that’s identical in colours to my own. Should I ignore and just go with what I’ve bought? I can’t afford to buy again and it took forever to find a good fit. I’m worried we are going to look like bookends! Any advice on how to handle please.
