I managed to get my hands on a lovely Schott shearling jacket ... shawl collar and raglan sleeves ... at an absolute steal of a price. Unfortunately, the jacket is several sizes too large for me to wear, and looks like an absolute tent on me. Other than that, I absolutely love it, and the shearling itself is so thick and wonderful ... the sort of stuff I never see ... that I'd love to salvage the jacket. Is this something that a good leather specialist can do? Knock the whole jacket down a few sizes so it fits me well?
