Periwinkle (Lucy Hale) is a frost fairy. She is Tinker Bell's fraternal twin sister; born of the same baby's first laugh and match. She is small, slender, and hand-sized with fair skin, ice-blue eyes, snow white hair, pink blushing cheeks, and pointy ears and wears an aqua strapless dress that shimmers like ice with dark icy blue pants and aqua blue-colored shoes with white puffs on her toes and has clear sparkly fairy wings on her back, which are identical to Tinker Bell's.
