Summer is in full swing, so now is not the time to slack when it comes to your wardrobe. For a refreshing upgrade, try one of these celeb-approved fashionable must-haves that will surely bust you out of any style rut.

Maxi Skirts

Stylish stars like Rachel Bilson are stepping out in summery, full-length skirts, which can effortlessly transition from day to night. "When wearing this bohemian-inspired look, keep your top simple,” suggests celeb stylist Orlee Winer. "Allow the focus to remain on the skirt by pairing it with a solid-colored tank or tee." (An especially important rule for printed numbers.)

White Blazers

No more noir! "The white blazer has become a Hollywood summer staple," celeb stylist Monica Rose explains of the trend. "It is a lighter, more modern alternative to a black jacket or wrap." Cameron Diaz, pictured left, rocks hers with a breezy top and a tan skirt.

Cool Arm Candy

From woven rhinestones to neon skulls, Hollywood's newest funky bracelets come in a slew of fun textures and bright colors. (See them sparkle on Dancing with the Stars's Lacey Schwimmer.) Mix and match different styles, and don't forget to pile high! Nothing punches up a summer outfit like an arm covered with eye-catching bangles.
