An underwater dreamscape, this short-sleeved shirt by Kamehameha is dripping in dark and lime green algae. Hiding among the limu (seaweed), bright red coral and white spiny starfish are aqua-green Siamese fighting fish, known as the betta, a popular aquarium species. These fish are native to the rice paddles, canals and floodplains in the Mekong basin of Thailand, Laos, Cambodia and Vietnam.
