Spending life as an aquatic dweller doesn’t give one much opportunity to see land. Fortunately, this awesome collection of marine animal costumes allows the elegance of these sea creatures to float above water.
The vast array of animal life featured here is a dazzling display of nature’s beauty. From fish and crabs to lobsters and sharks. This collection covers all the DIY costume ocean inspired ideas.
Another phenomenal idea are the luminescent seahorse costumes. They are unbelievably more impressive that any costume available to purchase.
In addition, so many television shows have taken their lead from the deep blue waters. You will see homemade costumes of Nemo, SpongeBob, Shark Week and even Sharknado.
So enjoy the appealing mysteriousness of life below the surface of the ocean. If you create your own marine animal costumes, please share them with us here! We would love to add them to this inspiring oceanic collection!

This Lobster Dinner family costume was very simple to make and got lots of laughs. We dressed up our 10-month old baby as a lobster. The base of the costume for her is a pair of red pajamas. I used foam paper to make crustacean claws and stripes across her belly – just used tape to … Read more
I made this Octopus Baby Costume completely by hand using needle, thread, material, and a bathroom tub mat. I made this for my 1 year old grandson, measured the height he was then cut the material 1 inch above so it wouldn’t drag. It was like a dress below the bottom so he could move … Read more
The Homemade Killer Fish Halloween Costume Idea took me about two and a half days to complete.

My Homemade Angler Fish Halloween Costume was a real party pleaser! I used some foam from a couch cushion and carved it out to make the body of the Angler.

My Octopus costume was made by me! It took a long time but was well worth it! I got 3 pairs of purple leggings which I stuffed with polyester wadding, in a roll as to not get lumpy legs! I then put garden wire through the middle of each leg to create the curve at … Read more
