The dog days of summer often leave us feeling uninspired to the point that the very thought of assembling an outfit makes us sweat. Fortunately we've got some refreshing celeb styles that will perk up even the laziest fashion lovers. Today we're serving up our favorite warm weather looks just in time for your Fourth of July festivities.

Lindsay Lohan had the skies and sea covered with the aviator sunglasses and nautical stripes she wore during a recent Planet Blue shopping trip. We like how she chose to tuck in her striped top, as it gives the effect of a high-waisted short without actually going there.

Camilla Alves might be better known for her boyfriend (Matthew McConaughey) than for her personal style, but we hope that changes. Seen here attending her beau's Surfer Dude wrap party, we think her belted tunic/dress exemplifies the sort easy chic you'd expect from a Brazilian model.

Nicky Hilton's bright patterned mini dress, turquoise ring, and casual flip-flops are simply darling. We also like how this look would be equally appropriate in Malibu, Miami, or Majorca.

Cameron Diaz smacks of summer in this outfit she wore to LA's La Conversation. The Hawaiian-style print dress, short hem length, straw bag, and sandals make us want to hop a plane for some shaved ice.

Kate Bosworth rocks a great, neater alternative to cutoffs with her rolled jean shorts. Her loose fit, graphic print t-shirt is a modest partner for the short shorts while yellow flip-flops lengthen her legs.
