FWIW I have yet to get my hands on my normal size in the non-ribbed sleeve type leathers like Stooges though I did try the Bauhaus cut, but in a size 50 where the sleeves were too long. Perhaps a 48 would have fit better. YMMV
FYI: Usually a 48 but wear a size 50 in the Intarsia. Feels comfortable, but anything more than a tee would be ridiculously tight borderline unwearable. I fancy one of those L/S RO knits or tees would be fine though.
