Flowers/decor

So I’m not a huge fan of putting money into flowers for one day, and plan on using as few as necessary. I did go to school for floral design and plan on designing my centerpieces and wedding party flowers. Thankfully the centerpieces will be easy enough to put together that I won’t need to worry about a friend setting them up for me.

I am stuck though, I can incorporate my colors into the centerpieces, which is essentially just greenery. Would it be weird if I didn’t though, and just have the colors worn by the bridal party?
