I typically wear medium sweatshirts / sweaters / t-shirts across the board; however, this medium was over sized for me. I went with a small instead. The length of the sweater was at least 4-5" longer than a typical M sweater. I ended up ordering a small, and it's fit isn't exactly perfect, either...but it looks much better on me. It's a bit tight in my chest area, though the length -- both sleeve and height -- are more appropriate for my fit. Thanks to Eddie Bauer's return service, I was able to get a new one at no extra cost.
