I often wear white jeans in spring and summer as part of the whole affluent, European look: navy blazer, loafers etc.
I'm personally not convinced by them in an AW look, as they just scream impracticality. People do wear them in winter though, and some get away with it. There's nothing wrong with the outfit's you've suggested (though it's not a look I would wear) but I'm not sure what the jeans add. A pair of indigo skinnies would work just as well without the extra expenditure on Dazz washing tablets.
