I’m overwhelmed with decor and flowers...ideas help?

I’m getting married in late October, my colors are navy and blush with hints of burgundy. I’ve already got my bouquet and made two floral arrangements for the church. I’m leaning more towards real flowers for everything else. But, I don’t have the funds/ want to spend the money on a florist. I’ve thought about babies breath for bridesmaid bouquets, because of cost...but feeling like it may not mesh well with what I’ve already got? What do you think? Am I over thinking this? Thank you
