We contend that Mermaids aren't real no matter how many of those weird documentaries on the History Channel say they are! We need ireffutable proof... but wait a minute... there's been a new sighting and it's pretty compelling... this can't be, but mermaids ARE real and they've been sitting right here at Halloweencostumes.com this entire time! This is remarkable! We're looking through our spyglass here and we see mermaid costumes for kids and women both, from sexy to classic styles, and even mermaid costumes that recreate a certain animated character that loves to sing on rocks! Someone call a documentary crew because we've got the scoop of the century here! 

Whether you want a sexy mermaid costume, a stunning girls mermaid outfit, a goth mermaid costume, or even an under the sea warrior - we have it all!
