Oso’s take on the classic men’s shirt, the Guayabera Shirt, or “summer shirt”! This shirt style became popular for hot or humid weather (particularly in Cuba, the Caribbean and Mexico) and is known to have pleats that run down the front. It is often considered formalwear — but not our Oso take on it. Yes, it can be worn as a party shirt, but also as an everyday shirt. It’s as if we mixed the guayabera shirt style with a classic baseball shirt into one (the stitching from the back down the front of the shirt comes from classic baseball shirts). So good, we named it after the famous Jackie Robinson.
