Cameron Diaz and Kate Upton's Clothes in The Other Woman

Cameron Diaz had fun on the set of The Other Woman in a black-and-white floral-print dress. Score a similar mini in a dark palette to re-create Cameron's look this Summer.

Cameron Diaz worked a striped bandeau bikini by Marie France Van Damme while hanging out in the water. Stripes are a classic that won't go out of style, so it's a smart Summer buy.

Kate Upton flaunted her bikini body in a berry-hued triangle suit in the Bahamas. If you want to reveal your figure, then go for a similar style.

Leslie Mann filmed scenes in a sporty blue bikini. This style is good for those with a sportier frame.

Kate Upton and Cameron Diaz worked two totally different looks on the set of The Other Woman. Kate was laid-back in denim cutoffs, while Cameron was polished in leopard and white denim. Both are great Summer styles and you probably already own similar pieces in your closet.

Leslie Mann's character was a vision of happy in her ladylike ensemble. Get the look by tucking a bold tee into a printed skirt, then add equally loud sandals.

On the set of The Other Woman, Cameron Diaz showed off the perfect professional-chic ensemble. To get her look, tuck a sleeveless white top into a navy pencil skirt, then add a gold belt, pointy white pumps, and a white structured bag.

A little white dress like the one Cameron Diaz donned on the set of her new movie is the ultimate way to beat the Summer heat. Add a crossbody bag and ankle-strap sandals to finish.

For something more casual, look to Kate Upton's The Other Woman wardrobe. Match a sleeveless, printed button-down with denim cutoffs, wedge sneakers, a statement bucket bag, and Ray-Ban Wayfarers.

Use your crisp white blazer to tame a loud-print dress à la Cameron Diaz on the set of The Other Woman.

If you prefer sportier cuts, pick a tank dress in a fun hue like the yellow one Cameron Diaz wore while filming a scene with costar Leslie Mann.

A red dress never, ever goes out of style. Just ask Cameron, who stood out in her long-sleeved version. Add neutral accessories so that your dress can take center stage (as it should).

A black-and-white knit sweater — and a glass of wine! — is a good way to beat the Summer chill at night.
