TBB's measurements aren't as meticulous as a Japanese stockist, but their sizing recommendations are pretty good. Just as an example, the "waist" measurement they give for the B1P pant is 32" – which is the same as they give for the fatigues. Having both pieces, I can tell you unequivocally that the waist band measurement of both pants is not the same.@tobiasfunke
– You're a touch smaller than I am, but I've bought my 19th Century BDs TTS this season at a M. The shoulder to shoulder measurement is a little bigger than what you'd find on a more fashion-forward brand like Ervell, but it's not anywhere near 19". Mind you, it's not
a slim-fitting shirt. They're a little blousy if you tuck them in, which isn't a big deal for FW when you'd expect to wear a jacket most of the time – or just leave them untucked.
Sizing down fails to alleviate the issue because the sleeves shorten considerably, which is compounded by the smaller shoulder to shoulder measurement. The high side gussets are also problematic because they can come up so high that you can't tuck the shirt in and leaving it untucked risks exposing your (read: my) muffin top every time I move my arms or lean over.
