Purchased from Business Shop Takakyu. The collar has subtle tucks, a simple yet dynamic design. It's a thin type, so it was easy to wear even in hot weather when paired with a jacket. The slightly glossy fabric makes it easy to look stylish even when worn casually! Other sizes and colors of the same design are also available. (Light Green x Size M) Discounts available for multiple purchases! Please let me know in the comments before purchasing. Color: White Pattern/Design: Solid
