It's a Disney Princess movie. Still, it either was or wasn't a favorite animated classic for you as a child. And either way, you've found yourself here today looking at men's Little Mermaid costumes. Whether that's because you were asked by your partner or your daughter to place Prince Eric, King Triton, or one of the sidekicks, or because you've simply decided to enjoy the things that make you smile we've got your back!

So, who's it going to be? Prince Eric? We've got the perfect look! Our Made By Us Prince Eric costume provides all the essentials and comes in sizes up to 5X. Love the look but looking for an option that saves a few coins? Try our deluxe Prince Eric that retains the signature look but pulls back on a few of the shinier finishes.

Want to boost that shine? It's time to embrace your inner merman with King Triton and similar styles. Our Disney King Triton swaps a bare chest for a shimmering gold sequin top and fitted pants that have a slight sparkle and attached fins. Pop on the crown and gauntlets, then decide if your King Triton needs the white hair and beard or if he's rocking your natural hair style.

If you're turning away from the Disney style, our Poseidon men's costumes are great! With as much sparkle but a few more ancient lore-type details and accessories, this one's ready for Little Mermaid retellings or Greek myth costumes—essentially, this option ensures you're getting your money's worth with versatility! Of course, if you're looking for something more sassy than regal, our just as versatile but simpler salty merman costume can't be missed!

Joining a group costume but the leading men are already claimed? Perhaps you've been invited to a sidekicks only costume party? Either way (or for many more) you've got to give our Sebastian, Flounder, Flotsam, and Jetsam costumes a look.

For easy wearing, our Flounder tunic is unbeatable. Full of character and thoughtful detailing, the pullover costume is sure to shine as its smile proceeds you into any room. Simply slip it on over your preferred clothing and you're good to accompany Ariel, bicker with Sebastian, or make the crowd giggle at the unexpected solo choice.

Just as smile-inducing, our Disney Sebastian is ready for Little Mermaid adventures. It'll just take a few more steps to get looking like the bossy and sensible crab with a heart of gold. Crack a few shells with more laughter when you pick our other crab costumes to pair with Sebastian as cousins, friends, and more. Or really break expectations with a lobster costume—you know why.

Flotsam and Jetsam join the party as easily as Flounder with a full-coverage pullover tunic and headpiece with interchangeable eyes that let you mix and match which of Ursula's poopsies you are. Because, just like any costume chosen in this collection, you're set to enchant!
