I'm newly obese (not huge, skinny most of my life) but can't find long-sleeve shirts or sweaters that fit. I'm 5'8 and my arms are short, around size 32.5. I wear a large in most shirts but an X-large if it is a small X-large. The sleeves are always too long if I order a long-sleeve shirt or sweater in my size. What should I do? Is there somebody I should buy clothes from specifically for my shape? Should I roll my sleeves up?
