i love white. and yes, white after labor day is totally OK. i actually love white denim in the fall and winter. pair them with sweaters and booties to make them season appropriate. in this case, i wore sneakers because these stan smiths go with every thing (and they're so comfortable). and i threw on a black blazer to make my all white look more fall-ish.
