Mermaids and sirens sing their songs of death, but who do you think does the heavy lifting in the ocean to make sure noone comes back with footage? The mermaid mafia. This costume includes pants, shirt, and wig with crown. This is great on its own, but could be even better with the other costumes and accessories available in our store!
