Here is my take on Princess Marina from Toei's The Little Mermaid made back in 1975.

I re-rooted her hair with Lemon Zest saran doll hair I bought off of Shimmer Locks, I made her hair piece and edited two colored mermaid tails to make her tail. The mermaid tail is made of iridescent fabric that shines different colors in the sunlight. Photos don't do it enough justice.

I enjoyed customizing this doll a lot.
