Try Eddie Bauer, LL Bean, Lands' End. My newest rain trench is from Eddie Bauer, the "Girl on the Go" trench style. Mine is the indigo color with a flattering subtle vertical pattern, it does have a zip-off hood. I size up so I can wear layers underneath. The coat also comes in a zip-off liner style.
