A SURE THING: A light, bright dress will keep you fashionably cool, even if your luck starts to waver. The coral silk/cotton blend Esley sundress flatters with a deep v-neck and preppy ruffles. Pair it with pearls or gems for the full effect or simple metallics for something more subtle. You can pick it up at Twirl in Hillcrest for $58 (also in green).
BRIMMING WITH STYLE: Around the corner, The Village Hat Shop has an impressive variety of chapeaus ranging from feathered to foppish. There are no set rules for the size, shape, color or style of hat you choose, and you don't need to match the shade of your dress. However, some coordination is desirable and a wider brim will save your skin, so try out this black and white Jeanne Simmons Tiffany Widebrim for $18.95.
SURF SPRAY: Unless you've got some serious money to burn, the bulk of opening day is spent under the sun. Unfortunately, your skin will also be spent if you don't prepare accordingly. Neutrogena makes an arsenal of affordable products to help with that task. Their Healthy Skin makeup line offers foundation, powders and highlighters with built-in SPF 20 for well under $10 each, and their Ultimate Sport spray sunblock goes up to SPF 70. Once you’re lathered in sunscreen, keep cool throughout the day with Vichy Laboratories' Eau Thermale Thermal Spa Water. The light mineral spray is refreshing and full of great stuff for your skin ($11.50). All are available at San Diego CVS stores.
