However, the Italians (both men and women) are wearing their white jeans through the winter with boots and sweaters. I am glad to see the rule does not apply here and I finally worked up the courage to try my white jeans in January. No one even gave me a second look. Totally normal.
In June, I saw a girl wearing knee high boots and a leather jacket. I think it is brilliant to dress for the weather (and for what looks cute) rather than following a rule.
