First of all, here's an imgur album showing my problem. So, my sleeves are too long. Easy fix. Buuut when I stretch my arms out, it gets very tight on my upper arm and pulls the sleeve up quite a bit - now, would this be caused by the fact the shoulder seam sits down my arm a bit?
Which brings me onto my second question... I don't wear my shirts with ties, should I instead of getting shirts to fit my neck find ones that fit my chest/shoulders instead?
