Prospective Flow Riyu Shirt
Drawing from the relaxed tailoring of the Meiji era (1860s–early 1900s), this oversized short-sleeve button-down merges vintage sensibility with contemporary ease. Cut from 60% linen and 40% cotton, this lightweight shirt is garment-dyed in faded black. It features a graphic block-color layout with very subtle contrast between the pocket and lower right-hand side of shirt. A structured spread collar with tight stitching, and blackout buttons for a simple look. The result is a thoughtfully constructed, laid-back essential, ideal for elevating off-duty dressing with understated sophistication.
