BEST: Tori Spelling’s bright blue shorts were a hit with fans at Disney’s World Of Cars event on August 11, but their vibrant color seems to be a little blinding for daughter Stella, who hid her eyes from the glare!

WORST: Former fashionista Mischa Barton has been stuck in a serious style rut for a couple of years and dug herself in even deeper with these oversize denim shorts and sloppy bikini top while vacationing in chic St Tropez.

BEST: Julia Roberts showed off her fabulous pins in a pair of designer Diane Von Furstenberg shorts at the Eat, Pray, Love premiere in New York City on August 10. With her upper body covered in a tailored Stella McCartney jacket, the 42-year-old actress was all long legs and big smile!

BEST: Kelly Ripa braved the humidity of New York City on August 11 in a comfy, casual outfit that was a refreshing change to the designer dresses she wears on Live With Regis And Kelly. Ripa was spotted earlier in the day in the same outfit but wearing high heels – the savvy TV host wisely decided that flip flops were a smarter pairing for her patterned shorts.

BEST: Rihanna can do no wrong on the style front! It takes a lot of courage to pull off a pink blazer, striped top, polka dot heels, denim shorts AND red hair, but somehow the singer makes the mish-mashed outfit work.

WORST: New cast member Deena Cortese needs to stop taking style tips from co-star Snooki! These white Jersey Shore jersey shorts are not flattering for the pint-sized guidette’s legs.

BEST: In town shooting the new season of Gossip Girl, fashion forward Blake Lively rocked out at Rihanna’s concert on August 12 in New York City in Affliction Black Premium Lizzie shorts that flattered her endless legs and sleek new hairdo.
