I don't take into account sequels, and the sisters aren't that pretty in the first film.

Aquata, Adella, Alana, and Arista are all prettier in my opinion.

no way i think arista, adella, aquata, attina and alana are prettier than ariel. poor andrina, she has a beautiful face but her hair is so ugly =(

def

I think Attina is the prettiest

I think Ariel's sisters are all ugly they're hair is weird they're eyes look funny they're faces are ugly and look weird and I don't mean weird and funny looking like just how most cartoons look they're just ugly IMO

I like Andrina's hair.
Anyway, they are all beautiful, imo. Arista is probably the only one who could equal Ariel, though, if I had to try and rank them.

wayyyy prettier
