Gothic Mermaid looks up at her prey... want to see me actually SWIMMING in this lovely black mermaid tail? Click the link to see the full-length video! This fabric mermaid tail is from Moonsong Magic. Normally, I swim in my silicone mermaid tails while I'm out in the lake. BUT! This fabric tail is so pretty that I even took it out for an October lake swim... which was cold, but well worth it!
