Someone from the internet drew what ariel would look life if she is real life. I think this is the starting point if you fancy her style and want to describe it to your stylist.
You don't have to have your hair colored red for your wedding but you can still hold on to that vibe. Like here, she use a star fish haircomb.
But the winner IMHO must be this one, I find it so alluring. Beachy waves in deep red and her makeup works too.
