Real vs Artificial Flowers

My planner and I are at spot where we are not agreeing.lol To save on funds,my bridesmaids and I were planning to make our own bouquets using artificial flowers.One of my bridesmaids made her own for her wedding and they were gorgeous. My planner would rather I use real flowers...Now we did some pricing and the amount is WAAAY out of my league.
She is stepping back a little and says "Okay we can use artificial for your centerpieces and bridesmaids BUT you have to have the real flowers."I looked at Costco and Sam's (who knew!?)they have lovely calla lilly boquets...but one of the things that I want the most is a bouquet with peacock feathers added....I'll add them myself if I have to....Of course they do not have customization added.🤦🏽‍♀️Can I just stick with my home made ideas?Are artificial flowers taboo at weddings?!#justtryingtosavemoney
