We used bright, clear yellow gingham fabric to make bon's shirt and pon's set. This bright yellow was bonpon's preference. They did several test weavings to get closer to the yellow they had in mind. The trademark eyeglasses embroidery is a royal blue that stands out against the yellow. "We made a spring-like shirt and set using bright yellow gingham, like rape blossoms. Wearing bright colors lifts your spirits! Enjoy your spring outings in clothes that stand out against the blue sky." from bonpon
