Recently, the concept of SDGs and a circular society has gained attention. Mass-market stores produce large quantities of clothing, and leftover garments are discarded. Our custom shirts are made to order based on the amount of fabric needed for each individual, resulting in minimal waste. Shirt tailoring is one of the most effective ways to realize a circular society.
