Wedding Wednesdays Q&A: Are Boutonnieres Necessary?

Q: I’ve been talking to some florists for my wedding and they’re all asking me what I need.  I’m not sure what I need, in particular things like boutonnieres and corsages.  I’m trying to keep the flowers simple to save some money.  Do I need boutonnieres?  Are they necessary?   Lots of good questions here,
