There is this irrational fear of wearing what after Labor Day that is almost laughable. I usually end up responding to those still gripped by this antiquated belief with "If God didn't want us to wear white after a man made holiday, he would paint the snow a different color."
The fact is, whatever season you are in, very few things look as clean and crisp as an all white outfit.
This look from Harper's Bazaar is a great example of how to wear white waaaay after Labor Day (not that you are confined to fashion rules such as that), and of course you won't pay Harper's Bazaar prices and still end up looking just as chic. Here is your look for less.
