Preppy dressing in the summer is all about bright colors and pastel hues. Nothing is easier than pairing a pastel oxford or polo with a pair of crisp, white chinos.
Pair complementary colors together so they stand out. Here, I've even paired gingham with stripes to mix pattern for more interest. This outfit would be perfect for a summer dinner party with its polished look created by the pocket square which brings out the darker blue in the blazer.
