If I keep it, any perceived or actual tightness will be gone due to the way leather molds and stretches. This leather is pretty stretchy and has no lining, so it will give a few mm. The only place I wish it were maybe 1/4" bigger is the chest - the waist is all good. Maybe it could be 1/2" shorter, but I won't stress over that too much. I am leaning towards keeping it at this time. Oh, and it looks great open, too - which is not the case a lot of times with leather.
And for sure... we are going to add prancing unicorns and super happy rainbows to the wall. Happy little clouds, too.
