Summer blockbuster season is in full swing and we're having trouble deciding which flick we should sit down and see this weekend: is it the "The Change-Up", an adult version of "Freaky Friday"? Or the scary sci-fi movie "Rise of the Planet of the Apes"? And let's not forget about the edge-of-your-seat drama, "The Whistleblower".

All three films feature fashionable leading ladies. Olivia Wilde stars in "The Change-Up" as a sexy legal associate, Freida Pinto goes primal in "Rise of the Planet of the Apes" and Rachel Weisz plays a police officer in "The Whistleblower". We took a look at each star's style stats in the following categories: Casual, Red Carpet and Beauty.

Each gal puts their own spin the looks, so we have to ask: which actress is your pick for most fashionable?

CASUAL: Olivia Wilde was spotted in Los Angeles in boot cut denim and white tee, while Freida Pinto kept comfortable in a similar look but paired hers with a rugged brown jacket. Elsewhere, Rachel Weisz ran through LAX in a pair of skinny jeans and ankle booties.

RED CARPET: Wilde arrived at the L.A. premiere "The Change-Up" wearing a structured Antonio Berardi sheath dress and matching crimson pumps. The "Slumdog Millionaire" star chose a Lanvin number for the 2011 amfAR's Cinema Against AIDS Gala and simple black heels. Rachel Weisz paired her red hot Valentino number with nude heels at a recent screening of "The Whistleblower" in NYC.

BEAUTY: The Nylon cover girl celebrated the mag's denim issue donning choppy bangs and honey brown low-lights. Pinto wore her locks in a very loose braid with face-framing strands at a recent premiere and Weisz pumped up the volume with bouncy waves.
