Anyone got any sizing advice for the millerain oilcloth field jacket? I tend to fall between small and medium for j.Crew unfortunately. I'm also considering the fatigue jacket, which would be a better fit for spring? Tried the millerain on last fall in my usual size and the fit was very good. Depends on what you want, but I'd say the millerain seems more appropriate for cool fall days than for spring. the fatigue is slightly lighter.
