1. Spongebob Squarepants costume

Buy Spongebob costume items:

  1. Yellow morphsuit
  2. White short-sleeved shirt
  3. Red tie
  4. Brown dress shorts
  5. Black leather belt
  6. Skater tube socks

Who lives in a pineapple under the sea? Anyone who grew up watching children’s television shows during the 2000s knows the answer to that question.

Absorbent and yellow and porous is he: SPONGEBOB SQUAREPANTS!

How could we start our round-up of the best Spongebob Squarepants costumes anywhere else? Sure, you could buy an inflatable Spongebob costume like everyone else and be done with it, but where’s the fun in that?

We’re focusing on realistic Spongebob Squarepants costumes here. Imagine Spongebob as the realest and most optimistic fry cook you’ll ever meet.

This is actually a relatively easy DIY Spongebob costume to make too.

Start with a full-body yellow morphsuit (or a hoodless morphsuit if the full-body sounds too claustrophobic). Then, you will need a red tie, a white short-sleeve dress shirt, and brown chino pants. Add a leather belt and some dress shoes (make sure they are polished within an inch of their lives)

Hike your red and blue striped tube socks as high as they are willing to go and you are ready. Or should we say “I’m ready, I’m ready, I’m ready!”

Optionally, chow down on a delicious, succulent Krabby Patty and you have yourself the best homemade Spongebob costume this side of bikini bottom.

Patrick Star (Spongebob) costume guide

2. Patrick Star costume

Buy Patrick Star costume items:

  1. Pink morphsuit
  2. Patrick Star shorts
  3. Pink trainers
  4. Blue tie
  5. Shirt wrist cuffs

Patrick Star is Spongebob’s rock-dwelling next-door neighbor and ride-or-die best friend.

When the iconic duo isn’t busy jelly fishing in Jellyfish field, Patrick occupies his time waiting for his best friend to finish work at the Krusty Krab so that they can get into all kinds of colorful and lighthearted antics.

Just like with Spongebob, you can take it easy with the ever-popular inflatable Patrick costume if you are in need of a last-minute outfit. However, for something a little different, this is how to make your own DIY costume at home.

Start with a pink morphsuit this time and get yourself a pair of Patrick Star’s iconic green and purple flower swim shorts. Now, you could easily leave it there – as that is pretty much all Patrick wears on a day-to-day basis.

However, you would be forgiven for feeling a little…underdressed? To class it up a little, find yourself a blue necktie and some shirt wristcuffs. There you have it, Patrick is nothing if not the epitome of class.

Alternatively, for a slightly more sexy Patrick costume – remember when he donned a pair of high-heel, knee-high boots and fishnet stockings in the Spongebob movie? Stripper Patrick is an image few of us will ever forget. And that could be you at your next costume party! Your friends are lucky to have you.

How to make your own Squidward Tentacles costume from Spongebob

3. Squidward Tentacles costume

Buy Squidward costume items:

  1. Turquoise morphsuit
  2. Light brown short-sleeve polo shirt
  3. Sailors hat
  4. Mini clarinet/sax (optional)

It is a sad fact of life that growing up means becoming more and more like Squidward with each passing day.

Ah, who are we kidding? We love it! Whether you have a costume party to attend or just want to run a relaxing bubble bath and channel your inner Squidward, this is a super easy and effective cosplay to make.

To make your DIY Squidward costume (perfect for adults and children alike) start with a turquoise morphsuit and a brown polo shirt over the top. Like Patrick, Squidward is a man with an exceedingly limited wardrobe.

While working at his much-despised job as a cashier at the Krusty Krab, Squidward wears a traditional sailor’s hat. However, there is nothing he loves more than kicking back at home with his much-loved clarinet.

Alternatively, if you would prefer a more sexy Squidward costume, might we suggest Handsome Squidward?

This is quite possibly the most aesthetically pleasing of all our featured Spongebob costume ideas.

All you need is a skintight brown leotard, a black elastic waistband with a gold buckle, a Handsome Squidward mask, and a healthy dose of tussled chest hair.

How to make your own Sandy Cheeks costume from Spongebob

4. Sandy Cheeks Costume

Buy Sandy costume items

  1. Astronaut costume
  2. Squirrel tail
  3. Squirrel ears headband
  4. Chrome winter boots
  5. Acorn patch
  6. Pink flower hair clip
  7. Acrylic globe helmet (optional)

Sandy Cheeks is the intrepid scientist and explorer who has taken it upon herself to document the strange underwater phenomena that is Bikini Bottom.

Sandy’s Spongebob Squarepants costume is a little trickier to make at home than some of the other entries on our list but it is absolutely worth it.

FYI: Sandy and Spongebob also make for the cutest couples costume.

As Sandy cannot naturally breathe underwater without the use of special equipment, she is often seen wearing her modified astronaut suit and fishbowl helmet. She also typically dons a pair of chrome boots and a pretty pink flower, fixed atop her fishbowl. On her chest, she proudly wears an acorn insignia as a link to her past, surface-dwelling life.

Finally, add a generously sized squirrel tail and a pair of squirrel ears. There you have one of the most adorable Spongebob Squarepants costume ideas we have ever seen.

5. Sandy (bikini) costume

Buy sexy Sandy costume items:

  1. Lilac purple bikini
  2. Purple mini skirt
  3. Prop squirrel tail
  4. Cowgirl hat
  5. Squirrel ears headband

When Sandy is kicking back safe and sound in her pressurized habitat, she likes to swap out her bulky astronaut costume for something a little more laid-back.

This is the perfect Spongebob costume for adults who want to flaunt their stuff. Sandy wears a lilac purple bikini and a matching mini skirt.

Not one to forget her roots, she often also wears a classic cowgirl hat (Sandy Cheeks is originally from Texas).

Like the last Sandy costume, don’t forget to add a cute squirrel costume tail and squirrel ears headband to complete this fun and cute look.

How to make your own Mr. Krabs fancy dress costume

6. Mr. Krabs costume

Buy Mr. Krabs costume items:

  1. Red morphsuit
  2. Blue short-sleeve shirt
  3. Denim jean shorts
  4. Black belt with gold buckle
  5. Crab hands and hat
  6. Canvas moneybag (optional)

Money, money, money, money!

Mr. Krabs is a man so obsessed with the green stuff that he literally dreams about it. As the proprietor of the infinitely profitable Krusty Krab establishment and the only one who knows the secrets of the Krabby Patty formula, he is rarely short of cash; though that doesn’t stop him from wanting more.

To make your own DIY Mr. Krabs costume, start with a red morphsuit.

Add a blue short-sleeved shirt with a white undershirt. Hike your denim jean shorts up to your belly button and fasten them tight with a black belt and gold buckle.

Should you want to go the extra mile, get yourself some fake crab claws and hat.

The finishing touch? Don’t forget your comically oversized canvas money bag. You’re gonna need somewhere to keep all those beautiful notes safe and sound.

Now, read on for the perfect father-and-daughter Spongebob costume idea.

How to make your own Pearl fancy dress

7. Pearl costume

Buy Pearl costume items:

  1. Pink leotard
  2. Pink tutu
  3. Red cheerleading pom poms
  4. White ankle booties
  5. Neon pink fabric paint
  6. Red lipstick

Pearl is Mr. Krabs adopted daughter. As a high-school student, she often struggles to fit in with her fellow classmates, particularly given the fact she is quite literally the size of a whale.

Nevertheless, Pearl was an inspiration to us all as children: Showing no matter our differences, the most important lesson we can all learn is how to be true to ourselves.

To make your own Pearl costume you will need to channel your inner cheerleader.

Pearl wears a pink leotard with a large ‘P’ emblazoned across the front and a matching tutu. She is also often seen with her red cheerleader pom poms. On her feet, Pearl wears a pair of block-heel white booties.

Finally, she is never seen without her immaculately finished lips, done up with a deep red lipstick.

8. Plankton costume

Buy Plankton costume items:

  1. Green morphsuit
  2. Eye patch
  3. Insect antennae
  4. Stainless steel bucket (optional)
  5. Ray gun (optional)

Plankton is the owner of the Chum Bucket and arch-nemesis of Mr. Krabs.

There is seemingly no length Plankton won’t go to in order to get his hands on the Krabby Patty formula. To date, he is yet to experience any meaningful success.

This is another very easy Spongebob costume to make at home.

The essential accessories are a dark green morphsuit and insect antennae. We also recommend using a simple eyepatch to recreate Plankton’s one eye: the same as the Spongebob Squarepants live-action musical.

Optional accessories include a stainless steel bucket (or chum bucket, if you will) and a ray gun.

We recommend the same toy gun featured in our Rick and Morty costume roundup as it just has such a clean and cartoon-style look to it.

The bucket can also serve the dual purpose of a cool Plankton costume accessory and an ice bucket to keep your beverages cool.

9. Mrs. Puff costume

Buy Mrs. Puff costume items:

  1. Red mini skirt
  2. Blue short-sleeved shirt
  3. Chunky red heels
  4. Sailors hat
  5. Bolo tie

Mrs. Puff is the local driving instructor for Bikini Bottom.

She spends an awful lot of time coaching Spongebob who – try as he might – can never quite pass his driving test. Mrs. Puff’s origin story is shady at best and although little is revealed throughout the course of the show, there is compelling evidence that she is in fact a wanted fugitive with an assumed identity.

We’re not here to judge. We’re just here to show you how to make the best Mrs. Puff costume possible.

Start with a red mini skirt and blue short-sleeve shirt. Light blue tights are also a great addition and go well with a pair of red heels. Like many of the other Spongebob costumes, Mrs. Puff benefits from a traditional sailor’s hat.

While Mrs. Puff’s past might be a little sketchy, perhaps we can gain some insight from the yellow bolo tie she wears. Has another southern gal found her way to Bikini Bottom, just like Sandy Cheeks?

10. Dennis (Spongebob Squarepants Movie) costume

Buy Dennis costume items:

  1. Black cowboy hat
  2. Red handkerchief
  3. Classic aviators
  4. Leather sleeveless motorcycle jacket
  5. Grey t-shirt
  6. Black denim jeans
  7. Belt with skull buckle
  8. Motorcycle boots
  9. Fingerless punk glove
  10. Prop serrated knife
  11. Shoulder pads

Dennis is the primary antagonist of the original feature-length movie and spends much of his time trying to crush Spongebob and Patrick under his sizeable boot.

This cosplay requires a little more work than some of the others featured on this list but there is no denying that this might be one of the coolest Spongebob Squarepants costumes you could possibly make.

As a badass biker mercenary for hire, much of Dennis’s outfit is inspired by rebel motorcycle culture. Everything from his leather sleeveless motorcycle jacket, red bandanna, chunky boots, and punk fingerless glove, to his skull buckle belt all draw heavily from this gritty subculture.

Some everyday items, such as his grey T-shirt, black jeans, and classic aviators, you might already own. Other accessories like his distinctive black cowboy hat, cosplay knife, and biker shoulder pads, maybe not.

The extra work required to make Dennis’s costume work is absolutely worth the effort. This is one of our favorite Spongebob Squarepants costumes.
