Ha ha ha ha, I was just skimming through all the comments and I was about to add a dissenting positive vote on 6 and then I saw Joy's comment. She's so right! You have a taller and more angular frame than me, I think, so you can pull off the oversized 80s blazer look quite well. But if it's not your look, no need to force it.
I agree with everyone that almost all of these fit you quite well, so it's more a question of style than fit. I am guessing that you got a little smaller since buying some of these?
#1 is amazing. Very current yet retro. The jean jacket is also perfect.
2 and 8, and maybe 4, look dated to me (4 is just so different from my own style that it's hard to evaluate, and the sleeves are cut wider than they need to be). 8 also just looks too big.
The Theory blazer might be a touch too big in the shoulders. But it's such a classic, and it really looks quite good, so I'd be tempted to hold onto it.
I also struggle with where the shoulder should sit. I prefer boxy cuts with sharp shoulders (almost masculine fits) and I have wide shoulders for my overall small frame. If I put the shoulder seam closer in to my neck, I feel too round-shouldered. Almost all of my questions on YLF come down to me worrying that my natural impulse to size up is wrong.
