This is a set of two "i-shirt" shirts from Perfect Suit Factory (both size S). The retail price is around 5,000-6,000 yen per shirt. https://perfect-s.com/contents/psfa/ishirt/ Please check the images for details of each shirt. I liked that they are relatively slim-fitting and highly stretchable. There are no noticeable stains, but please refrain from purchasing if you are sensitive to items stored at home. ⑤ i shirt urban model Button-down, size S, neck 37cm, sleeve length 80cm ⑥ i shirt urban model Size S, neck 37cm, sleeve length 80cm
