At 86-70-93 the size of M sat well (shorts are not in the guise, but not an oversize, as wanted). The shirt is the opposite, an oversize. The sleeves are a little ridiculous. Like 3/4, but not quite. I'll turn around, most likely. Who wants an oversize, at its S-M take L, Fabric is good. Buttons change the color of the fabric. The color, by the way, is beautiful. I'll wear a suit on the beach or at home.
