Hello! About 2 weeks ago, I bought myself an eastman californian jacket which felt really snug at first, especially in the armpit area. Over the 2 weeks in which the jacket was worn regularly, the leather has become softer and the jacket is therefore more comfortable to wear. Since it was tight in the armpit area at first, I now notice that the seams have stretched noticably (see pictures). I am now wondering if this should be a concerning sign or not. Would do you think?
