Here’s the tezomeya specs. @Double 0 Soul I suspect the 170 measures smaller in the chest right out of the wash and stretched out slightly when I put the shirts on for the fit pics.
size 170 - p2p 52cm, length 59.5cm, shoulder 43cm, sleeve 21cm
size 175 - p2p 53cm, length 63.7cm, shoulder 44cm, sleeve 21cm
