1) Jellyfish

Find an old umbrella and attach streamers, feather boas, bubble wrap, tinsel, battery-pack fairy lights or just about anything you can find and you've got yourself a Jelly!

2) Mermaid

A real classic costume. Just cut up a tutu and attach it to the end of a skirt, wrap up in a net and add some shells! For a bonus make-up tip, put fishnet stockings over your face and brush on some blue and purple eye shadow for the illusion of scales!

3) Anenome

Perhaps not the most eco-friendly, but a very effective costume! Twist balloons together and attach them to yourself with string!

5) Scuba Diver

Is this even a costume if it's what you're wearing every weekend? Nonetheless, carrying around a tank on your back all night would be tiring so replace it with painted fizzy drink bottles and you're away!

6) Sea Turtle

There are a couple of different ways to do this one! Paint an oven dish and attach straps, make a shell out of cardboard or attach a mosaic of green paper plates, the choice is up to you!

10) Sailor

No nautical-themed halloween list would be complete without a sailor and the best thing is you probably already have most of the costume elements in your wardrobe! Simply find anything navy, white, red, or stripy, origami a hat and soon you'll be sailing on the high seas!
