I'm sure your mother told you to lather on your SPF so you don't get skin cancer, but sometimes it's just a smart move to stay in the shade. There's nothing nerdy about being pale — especially when you're hanging under this stylish Crate & Barrel Trovata Round Umbrella Cover ($99, reduced from $169), which blocks out 98% of the sun's UV rays. Its seaglass and khaki colored stripes will show all of your patio guests what a true sophisticate you are. More importantly, its Sunbrella fabric will stand up to the elements (unless maybe you encounter a natural disaster), so there'll be no need to replace it next season. Now all you need is some outdoor dinnerware and a good margarita recipe, and you'll be set for the season.
