Hey everyone i sooo need help here

i feel like i have a vision in mind but i have NO idea how to execute it.
my dress is a ruffly chiffon ballgown super flowy pretty, and i have a chapel length veil with very few swarovski crystals for just a TINY bit of sparkle. i hate bling so its perfect.
for my accessories i'm wearing my mom's beautiful pearl necklace for my something borrowed, and my grandma's pearl stud earrings as my something old.
i want my hair to be a half up-do, curly and i'm planning on getting extensions so my hair looks thicker and a little bit longer....
i want to put something in my hair, i would love for it to be a trimmed peacock feather or two, held with a cluster of pearls...somthing like that....but basically every picture i find, the hair fastenater or accessory is on the side of the bride's head. what i'm wanting to do is to put a clip in my hair to replace the veil for the reception, so i still have something in my hair.
anyone happen to have any pictures with examples or anything for me to see? i just don't know if it would look weird to have it on the back of my head, but i just want it to replace the veil so my hair stays in tact and i think it sounds cute. \
what do you think?

i love these they're so cute.
i also thought about a headband but again, i hate bling and all i seem to find is things that are full of diamonds, even the pearly ones....i would not want it to be big, and i would not want it to be a tiara....but i think it looks nice to have that little something in the hair like this:
sooooo confused
