1.) Wear cool fabrics. Silk, satin and such are an obvious no. For one, too dressy. Secondly, when you sweat it will cling and get wet spots...not a cute look. Stick to thin cottons, linen, and other such natural fabrics. Stay away from the synthetics such as polyester.
2.) When in doubt, stick to the basics. A t-shirt and shorts will do just fine. Try stepping it up a notch by going with a shape or style that is more current. We love a pair of distressed cut-offs with a loose-fitting tee.
3.) The looser the better (in regards to your clothing). Breezy t-shirts, peasant tops, and dresses will keep you cool while still allowing you to have a little style.
4.) Don't forget to accessorize. When dressing for practicality and comfort (i.e. usually plain and basic), accessories are your best friend. They can take you from blah to hot football mom!
