Boutonnieres

Fathers can, even grandparents, but not necessary.

Mothers / Grands can have corsages or boutonnieres.

I agree with PP but not necessarily if you need to cut back in your budget.

The groom, groomsmen, the bride's dad, the groom's dad, the ring bearer, any ushers, both sets of grandfathers, a male officiant, and any male readers should all wear a bout according to Google. But I don’t think all that is “required” nowadays. Bouts can get expensive adding up how many one has to get!

It's completely up to you. You can include them. I think I would if we were going that route.

Traditionally any other men involved in the ceremony, parents, and grandparents.

Our dads wore them. If we had grandfathers, they also would have worn them.

Our mother's and grandmothers wore corsages.

I think it depends on who you plan on having walk in the processional. For example, both of our moms walked in the processional so they both had corsages. My brother and my husband's younger brother were in the wedding so of course they had boutonnieres. My husband's older brother wasn't in the wedding nor did he walk in the processional so he didn't have a boutonniere. My husband choose not to include his dad or his dad's fiancée in the processional, but they were introduced during the grand entrance into the reception. I left it up to my husband and he choose for his dad to have a boutonniere, but not for his dad's fiancée to have a corsage. He felt that honor should only be for the moms plus he barely knows his dad's fiancée. I would've liked my grandparents to have been included in the processional and have corsages/boutonnieres, but since my husband doesn't have any living grandparents he wasn't comfortable with this. I think it all comes down to a personal choice.

View Quoted Comment This is a good point! Gives me another perspective to decide!

Our fathers had boutonnieres for our wedding. Are grandfathers are no longer with us, but we would have given them boutonnieres as well if they were

It's generally only parents and grandparents as an unspoken signal to guests they are family. Beyond that, it could get confusing/awkward if someone goes up to congrate who they think is dad but it's a distant uncle.

My parents and siblings who weren’t in the wedding party got it

Typically traditional pin boutonnieres go to the groom, groomsmen, officiant, fathers of the couple, and grandfathers of the couple, sometimes siblings of the couple if they are not otherwise in the wedding. Mothers and grandmothers of the couple wear pin or wrist corsages. But absolutely none of this is necessary or required.

Our moms didn't care if they got a corsage so we opted not to do them (they're kinda itchy, no one wants to put a pin hole in a beautiful dress, and they're an unnecessary added expense). We are planning to do boutonnieres for our officiant and my FIL in addition to my husband and his groomsmen.

The only other thing I'll say is whether or not you do boutonnieres or corsages, just make sure you treat all similar rank family members and sides of the family equally. Don't get the MOB a corsage but not the MOG for example. But it would be okay to do flowers for parents and not grandparents if that is what you choose.
