I set up a day with my FMIL today to go dress shopping for her MOG dress. At some point last week (without knowing we had this set up), my mom mentioned that the bride's mom gets to pick her dress first. The idea kind of annoyed me because I want to just let people wear whatever they want so I just ignored it. It's not like moms are in the bridal party, and my mom is not the host of the event so who cares? Also, my wedding is less than 5 months away and she really needs to get something ordered. I know there's no way in heck my MIL will choose anything near as over the top as my mom so should I just proceed with this day of shopping? Should I say we should wait to order anything until my mom does?
