This shirt draws inspiration from the common left breast pocket work shirts popular from the 1930s to the 1950s.
The design dates back to a time when shirts were mostly pocketless. As industrialization grew in the 19th century, there was a need for shirts to be more functional for the increasing number of workers. The left breast pocket became popular, catering to the majority who are right-handed. Over time, the design evolved to include multiple pockets and other functional features to meet the diverse needs.
