I can't comment on the smell of white tanned leathers as I don't own any but others here can. I know @dji0 said his was like a rotting corpse which would definitely be far from a fishy smell. Doing the diluted lemon juice seemed to help as I can tell the smell is as not a strong as before. One thing I remember that I can compare it to is the salty smell of the sea. My gf and I went to the shore a few times this summer and it always reminded us of the jacket. Lol!
