Flower should and can be unique

You can do a few things to change it up for your wedding and make it extra special. What about having your bouquet be like your mothers. It would be honoring to her especially if she is there but even more if she has passed.
You can personalize your bridesmaids and have them each have one type of flower only with the color matching your wedding colors. You could even find their flower that matches their birth month.
Now lets talk centerpieces. You can take multiple matching vases and put them together to make a statement verses having one large vase. It would give you the same affect but then you could have certain guests take them on their way home. Then it would be a personal touch for them to take away from your wedding.
Remember your wedding needs to have your unique touches.
