I think pink, because it's such a girly color, and represents love

Oh, cmon. She likes red!

Or blue. The purple might be her favorite because her seashells are that color, and blue because, well, the whole OCEAN is blue. Ariel didn't pick that pink monstrosity, they just gave it to her to wear, so I doubt it's pink.

I know, but she seems like person who likes pink anyway

Brown wouldn't look good on her

Um I personally thought Green, but its not here so..

Her seashells are purple and out of everything this is what she probably would have had the most choice in. The cloths on land were provided for her.

Or pink. Girly colors.

Where's green?

Yeah, I wanted to choose green too.

Omg, I was sure I've put it, I had picture for it, I will add it now, although I know its kind a late

or pink

well i think so anyway.

Or blue cuz of the ocean

I always thought green. It's a strong color, but can also be soft. It's a bright and fun color.

Either that or purple, since her seashells are purple and she probably gets to choose what color her seashells would be.

i think its pink and green because most of her pictures she seems to wear pink or green.

no its turquoise its on google look on wikipedia
