Ok, so I booked my first meeting with my florist for 7/24.

He told me that I get to pick my flowers that day then I have to come back another time to do my sample centerpiece. How do I choose everyone elses flowers? My mom already has her dress so she can pick whatever she wants but his mom, sister in law, and sister have no idea and probably wont until the week before. I thought I should just ask his mom what her favorite flower is then go with that and as for his sister and SIL I am thinking just go with something neutral. What did all of you do? Did everyone tell you what they wanted or did you pick for them?
