Research the location, as summer in many places means hot and incredibly humid conditions. In this instance choose lightweight fabrics such as cotton and linen to stay cool. Leave the silk at home - although it's light in texture, it's an insulator and may render you miserable.
Step2
Check with the bridal party or someone close to them. How would they prefer the guests dress?
Step3
Opt for dressy, not formal, if you're unsure. Women will dazzle in a sundress or satin skirt, twinset, sling-back pumps and nice jewelry. A suit is most appropriate for men, with dress slacks, a dress shirt and tie a close second.
Step4
Wear comfortable dress shoes. Although you'll sit through the ceremony and dinner, dancing late into the evening is a definite possibility.
Step5
Take layers. Summer nights can get cool, not to mention the threat of an overzealous indoor cooling system.
Step6
Remember sunglasses and sunscreen for outdoor ceremonies and festivities. Stash an umbrella in the car in case a summer shower dampens the occasion.
Step7
Leave the glitz, glamour and sparkle at home. All eyes are on the bride today, so don't challenge her place in the spotlight with a long beaded gown or sexy cocktail dress.
