This week in the world of social media, it was all about spending time with fashionable friends and sharing sweet snaps along the way. Poppy Delevingne and Henry Holland played a game of telephone (with sparkly heels, no less), and Sienna Miller snuggled with her baby girl, Marlowe, during a daytime birthday party. Coco Rocha set sail across the Sydney Harbour as fellow model Bar Refaeli shaded her face from the sun during a beach day. Prabal Gurung posed with his high-profile celebrity pals at his Vogue x MAC Cosmetics event (just imagine being able to call Zoe Saldana and Diane Kruger your friends!), while BFFs Karlie Kloss and Jourdan Dunn hit the kitchen for a cooking segment. Cara Delevingne shared a snap of the "weirdest breakfast ever" — and can you guess which model mom got back to nature with a horseback ride to the beach?

The NBA playoffs are underway, but you don't have to be a basketball fanatic to appreciate all the amazing celebrity sideline style.

Meanwhile, Olivia Wilde opted to show her New York Knicks pride by wearing the team's colors: blue and orange. From coast to coast, fashionable stars have stepped out in cool ensembles to cheer on the LA Lakers and Brooklyn Nets, too — and we're highlighting some of our favorite courtside looks.

Lauren Conrad may be best known for her starring roles on Laguna Beach and The Hills, but over the years she has proven herself to be quite the triple treat. The blond beauty has blossomed into an author, designer, and beauty guru — not to mention one of our favorite celebrity social media fixtures. What we love most about Lauren's style is how laid-back, put-together, and incredibly accessible it is. She's got a serious knack for fusing high fashion with California beach babe, which is an aesthetic that we can all get behind. From embellished party dresses to glamorous red carpet confections, Lauren's signature style continues to evolve — and she's taught us more than a few styling lessons along the way. So get a pen and grab a seat, then take note of LC's most stylish looks over the years.

Kate Upton graces Vogue's June cover, and in addition to modeling equestrian-chic separates in the accompanying spread, she also does what she's become famous for — showing off her enviable figure in gorgeous swimsuits. Looking every bit the picture-perfect pinup girl in suits from Dolce & Gabbana and Chanel, Kate's high-fashion beach pieces looked impossibly cool when paired with classic Ray-Ban Wayfarers and a tousled updo. Kate nails the modern bombshell look, and we're considering adopting it as our very own this season — starting with a retro-chic swimsuit. Whether you pair high-waisted bikini bottoms with a structured bra top or rock a '60s-style one-piece with nothing else, it's easy to achieve a figure-flattering poolside look, and we're helping you out by rounding up some of our own. Click through to shop 16 of our most-loved suits for the season ahead.

Miley Cyrus is No. 1 on Maxim's annual Hot 100 list, after beating out a roster of sexy stars like Megan Fox, Cameron Diaz, Rihanna, and Beyoncé. She may have gotten her start as Hannah Montana — but judging by her edgy haircut, skin-baring ensembles, and the engagement ring that's (sometimes) on her finger, it's pretty clear that Miss Miley is all grown up. She's gotten progressively more experimental with her style over the past couple of years and has been mixing things up with microminis, strategic cutouts, and dangerously low necklines — not to mention a midriff-baring look or two. To celebrate Miley's hot Maxim news, we're taking a look at 10 of her sexiest red carpet looks so far. Click through now to see them all.

Models, designers, celebrities, and more descended upon Manhattan this week for the 2013 Met Gala, and made sure to share their punk-infused snaps throughout the event. In addition to those high-glamour photos, we also got a glimpse of our fashionable favorites in their moments of work and play. Hilary Rhoda had an unfortunate spill on the set, while her fellow model Coco Rocha showed off her most-loved color of the moment. Cara Delevingne cozied up to Karl Lagerfeld in Singapore, and Stella McCartney made a special visit to Rihanna's concert in London. Also hanging across the pond was Nicky Hilton, who shared a cool candid snap in front of a classic British phone booth, while Bar Refaeli warned against the dangers of skinny dipping — alone.

Our first lady isn't just a supercool mom and inspiring role model; she's a style maven, too. Michelle Obama is able to jump-start new health- and dance-related initiatives, attend summits and galas around the world with her husband, take her kids to school, and look amazing as she juggles it all. From the custom Jason Wu gown she donned at the president's inaugural ball to casual J.Crew separates, we love her signature style of mixing high and low brands. Her special attention on supporting new, young designers, her disposition toward wearing bright, bold colors, and her knack for showing off those amazingly toned arms are just a few more reasons why we love our FLOTUS's panache. And with yesterday's pretty floral Prabal Gurung sheath (to meet Prince Harry!) supplying our latest round of classic styling inspiration, we're taking a closer look at her best outfits yet.

Target announced today that it is collaborating with designer Phillip Lim on an exclusive Fall 2013 collection, slated to hit Target stores on Sept. 15. The range will feature over 100 items for both men and women, including apparel, shoes, bags, and travel accessories — all priced between $20-$300. We can also expect the collection to be rooted in a classic autumnal palette, and collaboration line aside, the designer will stick to his signature modern, sophisticated aesthetic. Phillip Lim explained that he's been "intrigued by the idea of a design evolution" since an early age, and is excited at the prospect of creating a collection "that would inspire — one that is cool and chic, but still very accessible." Does that mean we'll see a Pashli look-alike?

In honor of the designer's big collaboration news, we've rounded up some of our favorite 3.1 Phillip Lim runway looks over the years — as well as Target's video sneak peek and your first look at Lim's sketches.

Hold on to your (leather) hats: Madonna is being honored as the Top Touring Artist at next week's Billboard Music Awards, thanks to the worldwide success of her recent MDNA tour.

The international superstar, clothing chameleon, and ultimate risk-taker has brought so much good to our lives — and single-handedly ushered in tons of trends since she hit the scene in the early '80s. From Ray-Ban Wayfarers and fingerless lace gloves to cone bras and stacks of rubber bracelets (the original arm party, in our opinion), Madonna has a long history of setting trends and paving the way for fashion freedom — and if her punk-inspired look from Monday's Met Gala is any indication, it doesn't look like she's stopping anytime soon. We're taking a look back at the many trends that Madonna set into motion — click through to see them all now.

We love seeing the stars' behind-the-scenes moments as they celebrate at big events — and the Costume Institute Gala was nothing short of fabulous. Some of our favorite snap-happy celebs like Gisele Bundchen, Miranda Kerr, and Stella McCartney got dolled up in their finest punk-inspired pieces and shared their fun, filtered photos from the red carpet and beyond. From the dressing room to the afterparties, we've rounded up all of the cute candids from the evening's fashionable festivities — click through to see all of them now.

The Costume Institute Benefit at the Metropolitan Museum of Art never fails to bring out the big guns — after all, where else can A-list celebrities, designers, models, and fashion insiders rub elbows . . . in couture? For last night's Met Gala, fashion's finest converged to celebrate the Punk: Chaos to Couture exhibition, which honored punk's impact on high fashion over the past three decades (and counting). As is customary for this event, celebrities and models arrived on the arms of their favorite designers and hit the red carpet with their superstylish significant others and fashionable friends — so we're rounding up the well-dressed duos (OK, there may be some trios thrown in there as well) from the night's rock-'n'-roll-inspired red carpet.

May is here, which means a fresh new crop of stylish celebrity candids to pore over. This week, Candice Swanepoel showed off one of our favorite Summer trends, while Rachel Zoe gave us a glimpse at her official CFDA member card. Chrissy Teigen had a slight wardrobe hiccup before heading to the White House Correspondents' Dinner, but was still able to turn it out in time for the big event. Rihanna and Zoe Saldana sported bad-ass looks from Mary Katrantzou and Balmain, respectively, but it was Brian Atwood's giant shoe delivery that really had us talking — can you guess what gala he's prepping for?

With the Met Gala paying homage to the Punk: Chaos to Couture exhibition, it's no wonder why we've got rock 'n' roll on the brain. Designers like Vivienne Westwood and Jean Paul Gaultier and big-time brands like Balmain and Givenchy all injected a punk-inspired spin into their Spring collections — and while the runway looks can get a little over the top (this is a show, after all), getting in on the trend yourself can be much easier than you think. We like to cull inspiration from the greats — punk pioneers like Debbie Harry, Sid Vicious, Siouxsie Sioux, and The Ramones, who all made superskinny jeans, ripped shirts, cutout dresses, and studded leather de rigueur. To celebrate Monday's big event, we've styled up three punk-inspired outfits that will have you looking like you're straight out of CBGB. Click through to see and shop them now.
