Ocean Halloween Costumes Roundup

Just like our new children’s book, Shalloween, this roundup is full of fun, ocean-themed Halloween spirit that will delight all ages.

Shalloween - Front CoverTo celebrate our new Halloween children’s book, Shalloween, we’ve got a roundup of ocean-inspired Halloween costumes for you today!

We’ve  got tons of costumes for you below, many of them in easy DIY-style too.  Mermaids, scuba divers, and sea creatures galore — dive in!

And to go along with your ocean-themed costume, make Halloween even more fun with the adventure of Shalloween (on Amazon here)!

 

1. DIY Scuba Diver Halloween Costume

Such an adorable idea!  Soda bottles are used for air tanks (secured by electrical tape), along with simple black pants and shirt, and a mask and snorkel.  There’s even a “weight” belt made out of electrical tape and hair curlers!

2. DIY Simple Shark Costume

What a great idea to use a sweatshirt hoodie for this costume!

5. DIY Stingray Costume

Here’s one that’s great for last minute scrambling! We love the details of the mouth and gills on the underside to make it more real.

6. DIY Starfish Costume

This simple cardboard cutout uses a pool noodle for the tube feet!

7. DIY Lobster Costume (2 options for DIY)

This Martha Stewart tutorial is complete with a claw template and instructions that are adaptable for any age.  Don’t you love the ping pong balls as eyes?

And this baby lobster costume isn’t DIY, but it’s just so clawfully cute!

10. DIY Mermaid Costume (3 options!) + Tiara (2 options!)

Being a mermaid is a dream for many little girls (myself included!) and is a timeless costume that all ages will adore.  I just love mermaid costumes, so I decided to give you several options.  To top off whichever one you choose, there are two DIY tiara options that are fit for a mer-princess!

Here’s a quick-sew version with stunning sheer organza scales, complete with a video tutorial:

Here’s a no-sew option for those of us that are a little more challenged in that area:

No-Sew-Mermaid-Tails

And here’s one with coffee filters for the scales that the kids can color themselves!

DIY-Mermaid-Tail-for-Kids

To top the mermaid costume off, here is a DIY royal addition of a sea-jeweled tiara.  Try and find faux starfish and use shells that you’ve collected instead of buying them. (By doing this, you’re not supporting harmful harvesting practices that are hurting marine species.)  Click the picture below or here for the video tutorial.

Here’s one more tiara option, this one uses a headband:

Ok, I couldn’t resist adding one more: a mermaid baby costume!  I haven’t gotten into crochet yet, but this looks like it might be a simple design to replicate for those of you who know crochet.  Is this not the most adorable mermaid costume you’ve ever seen?

Shalloween - Front CoverJust seeing all of these costumes makes us want to dress up too — what better excuse is there to dress up as a mermaid, scuba diver, or favorite sea creature!?

I was thinking of being a jelly fish this year and this round up gives me some easy ideas. Btw- I also have a Sea Turtle costume made from felt and a couch pillow, of all things – http://www.mindovermessy.com/diy-sea-turtle-costume/. Nicole @mindovermessy
