180/3 Miko Ribbon Blouse

This charming shirt features a slightly cropped length and softly gathered puff sleeves for a feminine touch. Tie the detachable ribbon at the collar for a playful Ivy-inspired look, or remove it for a more understated style—either way, it brings a lighthearted elegance to your outfit.

We used the finest Suvin cotton, spun as finely as a strand of hair and twisted into a three-ply yarn, then wove it tightly to create a crisp, structured fabric. The result is a shirt with a smooth, silky feel and a supple resilience—showcasing the quiet excellence of Japanese craftsmanship and the attention to detail that defines 45R.

Though it has the appearance of a dress shirt, it's made from 100% cotton, so it's perfectly suited for regular washing. It feels great worn rumpled straight from the wash, but also transforms into a polished shirt with a quick press—easy to care for, and easy to love.
