Which disney little mermaid (any of the 3 movies) character do I look most like??

For my cousins 6th birthday she's having a little mermaid party. Me and my cousins are the entertainment. So far Adella, Aquata, Melody, Vanessa/Ursula (I would dress up as Vanessa) attina, and arista are left for me to be. Which one do I resemble the most because it would make the costume alot easier. Thank you!!!
