Found it - very odd measurements. The shoulders were super tiny at 16.25" and the sleeves quite long (25.5"). I need something like 17" in the shoulders and 24" in sleeves (though I think my arms are shorter than most). Very odd - the small in this jacket definitely seems to be more like an extra small with long sleeves! FYI, shoulders aren't quite so slim. I used a tape measure so this might be a bit off but I get between 16.75 and 17" on the shoulders (16.75 if I don't hold the fabric taught -- this was confirmed by max-t on his "re-measure"). Other rough measurements -- chest at 19.50" and sleeves ~25.5"
