August, a prime wedding month, can be beastly hot. And speaking from experience—my cousin’s outdoor wedding was a balmy 108 degrees—picking the right outfit can make or break your time as a guest. Black is a classic no-one-will-notice-I’m-sweating choice, but there are a few other, more festive options, like a dress with a dark abstract print. The non-symmetrical pattern will help to conceal any perspiration problems. Another option is a loose silhouette with a playful skirt. The airy shape breathes and keeps your skin cool. Finish with suede shoes—better at blister prevention— bold jewelry, and a great pair of sunnies.
