*I am also selling on other sites, so in the event of simultaneous purchases, the earlier one will take precedence.* I have multiple of the same item, but it seems I won't be using them... I think the ribbed width is stylish. The flat measurements are approximately 51cm between the armpits, and approximately 58cm in length (from the collar and back seam to the hem). I am 169cm tall, weigh 59kg, have an 88cm chest (nipple level), and a 73cm waist (navel level). I usually wear a "S size" at MUJI and Uniqlo for a perfect fit, and this is a "XS size," but it feels about the same as a "S size." Thank you very much. #MUJI #MUJI
