Leather jackets - and stretching?

[Emo76]

I have my first ever leather jacket but am torn on sizing - the smaller one is a bit tight around the arms - do they tend to stretch?

Can't help you but am interested as saw a lovely one which was perfect but slightly tight around the bust.

No don't do it. They will stretch a bit, at least if the leather is very thin and supple, but will you ever get to that point?
