I feel your pain, so to speak. You get an item that is perfection aesthetically but for whatever reason it just doesn't work practically for you.
I bought one of those Grenfell raincoats and the liner is driving me crazy. It seems to bunch up inside the coat -- almost as if the coat were a 42R and the liner a 44R. Also, when I button up the coat and wak down the street for more than a couple of blocks, the coat works itself gradually backward off my neck and up the front of my torso -- so that it becomes tight around the chest/sternum (especially pronounced if I am wearing a scarf) and I have to yank the coat skywards by the back of the collar and pull it back up my neck so that the whole thing sits correctly again.
These are the sorts of things that it's just impossible to predict before purchasing, and using, an item. The coat works great without the liner and will be a terrific late spring/early fall coat but it's just not gonna work for me in the colder months when I need warmth but it's precipitating too heavily to wear my regular camel's hair topcoat. I guess I'm just gonna have to get one of those tweed/raincoat reversibles from O'Connell's.
Sorry to go off on a tangent, but it's bugging me.
