Stella McCartney

Wearing a blazer as a dress, like Rihanna just did in London, is a hard look to pull off, but a look that's easier to pull off than you expect is a printed jacket. It can lend instant jazz to everything from a little black dress to jeans. The singer paired her loud multicolor marble silk Stella McCartney blazer with round retro shades and ankle-strap sandals for her overseas appearance. For your version, wear a printed jacket — it need not be as loud, or even a blazer — with jeans and flats for a laid-back look, then pair it with a mini leather skirt and heels for a sassy night out. To get Rihanna's look, shop some of our favorite printed jackets below.

Rihanna and Brooklyn Decker posed pretty at the London photocall for their new movie Battleship. While it appears that the dresses they picked — Rihanna in Alexander Wang, Brooklyn in Stella McCartney — are vastly different, upon closer inspection, they share one sexy detail. Both frocks have exaggerated halter necklines that show off their beautiful shoulders. Notice how each cut caves into the center of their chests, revealing parts of their decolletage. It's a small detail, but one that can work major wonders. First, it can give the illusion of curves, plus it can also offer subtle sexiness, especially when the hemline of the dress is longer. Inspired by Rihanna and Brooklyn, we tracked down a handful of halter dresses with similar cuts, so shop your favorites below.

Brooklyn Decker appeared yesterday in a body-hugging Stella McCartney dress from her Spring 2012 collection — just the latest in a run of stylish celebrities to choose Stella's sexy, printed frocks. What is it that makes the dresses so irresistible? They're a little bit sporty, they're ultra fitted, and some have feminine embroidery and mesh cutouts. The combination of details makes these dresses ultra-special. Helena Christensen, Gwyneth Paltrow, and Nicole Kidman are among the stars to wear Stella.

One look at Amber Heard made us want practically everything she's wearing. The actress nailed denim on denim, pulling off a cool-girl balancing act between Spring trends and colder-weather staples — essentially, she outfits transitional dressing to a T. The trick is a deep camel-hued coat to keep her blue-jean pieces from overwhelming the look — not to mention a glittering pair of studded Jeffrey Campbell loafers and a covet-worthy Stella McCartney tote. Feeling inspired? Shop our key pieces to channel Amber's off-duty cool.

We always look to Beyoncé to showcase the latest trends, and she didn't disappoint when she wore her floral Stella McCartney pants with vibrant yellow pumps while out in NYC. The stylish star balanced her bold bottoms with a black silk blouse, two-tone Bottega Veneta belt, and blackout shades. Bright blue nails, simple hoops, and textured shoulder bag rounded up her city style. Beyoncé's look is perfect for Spring, so shop our picks of floral pants and eye-catching colored pumps to re-create this fashion-forward look.

With a handful of insanely-styled postbaby appearances, Beyoncé may just have solidified her place as one of the planet's most fashionable moms. This time she gives us a perfect take on Spring's printed-pants trend in a pair of Stella McCartney's tropical trousers from Resort 2012. The pattern's bold, but Beyoncé styles them with a silky black button-down that both tempers the print and lends an easiness to the whole look. We love that she accessorizes with a bright pair of pumps and a hot pink Bottega Veneta belt to complement the pant's brilliant hues, then finishes with a pair of cool-girl cat-eye shades. Tempted to try out your own printed pants? Shop our editors' picks to style up the same pair à la Beyoncé, or peruse our other options for a pair with a similar tropical print.
