- The aloha shirt is about as ubiquitous in Hawaii as the palm tree. Worn by just about everyone, the islands are always craving new takes on an old classic. Or at least that's what I tell myself when I enthusiastically agree to take on an aloha shirt collaboration. And as far as the aloha shirt is concerned, Kahala is legend. Together, we created the new 'Makai' shirt for their 2019 Summer Collection.
