orSlow is a Japanese label founded in 2005 by pattern maker Ichiro Nakatsu, whose name pairs "original" with a deliberately "slow" way of making clothes. The collection reproduces and reinterprets mid-century American workwear and military garments: 105 standard-fit and 107 slim five-pocket jeans, 1950s-cut selvedge denim, US Army fatigue pants, chambray and cotton shirting, and field-jacket style outerwear. Garments are cut in small runs at Japanese factories on vintage machinery, using loom-woven selvedge denim and natural fabrics that fade with wear. Distribution runs through specialist menswear retailers worldwide.

Does orSlow run big or small?

orSlow runs small. Treat the numeric tags as Japanese sizing and size up one from your usual US size on tops and outerwear (size 3 ≈ US M/L), while buying jeans to the tagged waist measurement rather than the number. Shoppers consistently report that orSlow's numeric sizing runs a size smaller than US labelling, so most people end up one size above their usual, even though the garments themselves are cut with roomy mid-century proportions.
