Anyone else kind of suck when it comes to costumes? Do you also end up resorting to a black cat or a skeleton every year because it’s easy (and everything you own is black)? No?

While scrolling through Pinterest for inspiration a while back I stumbled upon mermaid crowns. Some were ridiculously complex, some were dainty and delicate, but all had the same basis: a whole lot of shells. I had never considered trying to dress up as a mermaid for Halloween, but I was so drawn to how dreamy all the tiaras looked (and how easy it seemed like they’d be to make), that it was worth a try!

All together, the crown took me maybe two hours to put together (streaming movies from here slowed me down). Paired just right with a fish hook earring, soft waves, blue makeup, and some netting, and you’ve got yourself a mermaid queen.



+ assorted sized shells
+ mini-pearl beads
+ mini-crystals
+ adult sized tiara
+ hot glue gun


Essentially, start gluing to the tiara! Larger shells first, with smaller ones layered on top. I loosely planned out my design with the shells so that the mermaid crown was symmetrical, but ended up adding a few here and there for aesthetic that didn’t match up. Play around with it, and find the shape that works best for you.

I found that going back and adding the pearls and tiny crystals to the crevices helped pull everything together in a pleasing way. Remember, there’s no right or wrong way, so just have fun!

    This is super adorable. I like the idea of using the big pieces first and then finishing up in the crevices with the smaller pieces, it likely yields a more polished look than the other way around. Great job!
