I ordered this jacket in a small for myself and a Large in the Men's for my husband. His fits great and he loves it. I on the other hand, am still trying to find a size that fits. The small's sleeves were way to short for my arms. My arms are longer than average so I exchanged it for a medium. Too short again so tried the large. Still too short. The fit was fine in all 3 sizes, but I need more sleeve length. I hope the mens small works for me.
