Schott 118 sizing down/fit check question
I would like some advice regarding the perfecto 118. I love this jacket, got a size 38, but as you can see in the photos, it's far to baggy for me. Also, the sleeves are ridiculously long, and since I don't ride, if they end up on my wrist it would be fine by me.
Now I have the measurement charts from Schott, but since each jacket may be a bit different from another, I'd like to double check.
The question is fairly simple : for a slim fit, do I need to size down to a 34 or would a 36 be enough ? I fear a size 36 would still be too big in the shoulders and the sleeves.
To help any good samaritan, I am 178cm tall (5'10" according to the website), I weigh 66 kg (146 lbs), and my chest size is 96cm (38").
As seen in the photos, the body is large enough for a fold to appear in the back when I stand, and the shoulder seams fall down on my arms. Also, notice the room I have left when I stretch the waist from my armpit to the bottom of the jacket. If that's any help, I can close the belt in up to the 4th hole and still be comfortable.
For comparison, I also own a 508 size S, and the fit is spot on. I can provide a picture of it if that might help answer my question.
Thank you for taking the time to read all that, looking forward to you answers !
