My FMIL has asked my FH at least 3 times what I would like her to wear. Our wedding is in 9 months but we just started planning it and I really haven't thought about it, but it takes her a really long time to shop for things and he wants me to let her know. I looked up on the internet what the MOG is supposed to wear and it said ettiquite is the MOB picks first. But my mom is a last minute person, there's no way she is going to shop for a dress this far out. Would it be a huge ettiquite faux pas to give his mom some guidance since she clearly is worried about this and wants to start shopping? Or do I really have to let my mom pick first? So much of the ettiquite stuff is so dated that I don't know what is actually the norm about things like this
