Oh, that's too bad! Leather jackets are tough, no joke! I've given up on them for now, though I will be in Chicago in the fall with a giant All Saints store in the vicinity, so maybe I'll have some luck there? I am not holding my breath, but I feel like at least if I can try a bunch on and see what I like and what sucks, I can get a sense of what works for my IT self.
ETA: I can't tell you the number of things I've ordered online and returned over these past few months!! Many, many, many things! Mostly it's because I've gotten very picky.
ETAx2: You are certainly not busty!! Something about leather jackets can really emphasize the bust, I think. They are sometimes cut too snug through the bust, with no seaming (or inadequate seaming) and the material is so thick that it just molds around the bust....at least that's how they sometimes look on me! It's not your bust, it's the jacket!
