Kai Collection







Hawai'i is such a melting pot of people and cultures,
So we designed our mermaid print to celebrate our diverse history. Our Under The Kai print was inspired by the Little Mermaid and brings a unique island spin to the classic underwater tale -- adding an island touch with plumeria flowers, pineapples, and honu (Hawaiian Green Sea Turtles) scattered throughout. Designed in collaboration with local artist Suzanne Jennerich, whose art conveys such joy and cheerfulness that it’s as if she captured happiness and placed it on her canvas.
Fabric: 80% recycled polyester, 20% spandex
Care: Hand wash cold (without bleach), dry in shade.
Features: Lined
