Here's a crappy pic of my MA-1, about 7 months in... Shoulders are 0.5" wider, body length maybe 1 to 0.5" longer, and sleeves are an extra 2" long from what I usually wear... Sized that way on purpose, but up to you on how big a cluster it is. I do feel sometimes that the shoulders are too wide.
TOJ0 2013 with gray body, black lamb sleeves. Size 50 body, 48 body length, 52 sleeve length.
Tried on a few times, never worn out. Great jacket, but I realized I won't really wear this over my A-2 and MA-1. I'll throw in a TOJ tote if you really want it too.
Thanks for looking!
