Originating in the 1800s and worn by South American working-class men, the camp collar shirt–also know as Cuban collar–first became popular in the U.S. in the ‘50s. Since then, it’s become perhaps the newest and most sought-after “fashion item” of 2017.

There are various colors and patterns of camp collar shirts for sale from brands like Saint Laurent, Ami, and Dolce & Gabbana, but the Aloha-inspired one is probably the easiest way to get acclimated with this trend. Take notes from guys like Pharrell and Harry Styles and pop a few buttons. Or wear it completely open with or without a T-shirt underneath, if you're feeling froggy.
