Topshop has launched its festival collection inspired by Kate Bosworth today, which ultimately plays into the brand's multidimensional, interactive Summer campaign. From the acid-washed denim dresses and buckle-strap wedges to the pink-dipped feather angel wings, silver slip dresses (made for frolicking), and essential white separates, the lineup has Bosworth's mark on every piece.

"To gain learning experience from the Topshop design team has been a great opportunity for me. Our intent was to create fresh, wearable, and effortless festival pieces. I am proud of our work together and I adore these pieces," Bosworth said. Along with the collection debut, a short film shot by Bosworth's fiancé, Michael Polish, entitled The Road to Coachella, was released today, too. The dreamy video reveals Kate Bosworth roaming Mono Lake, CA, in a handful of effortlessly styled Topshop looks.

Sienna Miller knows how to start (and own) a trend — boho chic, anyone? — but her latest turn toward a more feminine fit-and-flare silhouette is something she has actually loved for years. While Miller's long-sleeved, light blue Matthew Williamson box-pleat dress may be the most recent example of her penchant for the girlier style, she has also stepped out in Topshop, Valentino, and Twenty8Twelve iterations. And it's not hard to see why she loves a fit-and-flare dress — and why, if you haven't converted yet, it's a really flattering choice for most body types. By cinching the smallest part of your waist and letting the skirt flare out over the hips, it creates an illusion of a bombshell-like figure. And for those of you who aren't after a totally body-con fit, this route touches on something halfway to formfitting. All the proof you need, according to Sienna Miller, is right here.

Along with her Bravehearts campaign, Taylor Swift partnered up with Keds on a very fitting shoe collaboration. The collection — which retails for $50 a pair — features 12 Champion sneaker styles reimagined. "The sneakers are really fun and easy to wear, and the designs reflect some of my favorite things," said Swift. Translation: the classic silhouette comes covered in a quirky sunglasses print; chevron patterns are tinged with mini guitars, paw prints, and flowers; and a stars-and-anchors motif provides a preppier slant. And if the shoes don't already speak for themselves, Swift sat down with stylist Zanna Roberts Rassi to talk all things collaboration, personal style evolution, and "dressing like a fairy." Keep reading for the best Swift style quotes, as well as a complete look at the Swift for Keds collection inside.

With Kate Middleton's baby bump finally showing, there comes a flurry of designers vying to dress her. And, according to WWD, they're more than willing to create custom maternity clothes for the expecting Duchess of Cambridge, too. Karl Lagerfeld, Nina Ricci, Vera Wang, and Donna Karan were among the designers to submit exclusive sketches, supplying a cool mix of daytime looks and more royally geared evening gowns, all tailored to highlight her bump.

To date, Middleton hasn't exactly been the poster child for wearing maternity clothes, having only worn one Topshop maternity outfit since her pregnancy was announced last year. Instead, she has opted to recycle her preexisting wardrobe with looks from Erdem, Mulberry, Armani, Max Mara, and Tara Jarmon — pieces that will remain wearable after the baby is born. Practicality aside, these designer sketches are undeniably fun. Click through to see them all, and tell us which design you like best in the comments below.

Rihanna's second River Island collection is slated to debut May 25, but that certainly doesn't mean you'll be in the dark about what's to come. The brand released a behind-the-scenes video today, which not only supplied us with our first look at the singer's latest Summer capsule, but also gave us a little more insight into what goes into a Rihanna collaboration. She chatted candidly with codesigner Adam Selman (fun fact: this isn't the first time she's worked with him — the proof here), revealed her favorite piece and where she plans on wearing it, and expounded on "gangsta" florals. To watch the exclusive sneak peek, plus a complete look at the first Rihanna For River Island collection and campaign, just keep clicking.

If there's one thing our moms taught us — besides proper etiquette, being kind, and so on — it's how to be our own stylish entity. From day one, these ladies have been there for our fashion highs and lowest lows. From dressing us in adorably girlie dresses to consoling us through some of our more questionable haircuts, behind every chic POPSUGAR editor, there's a chic mom. With Mother's Day on Sunday, it's time to take a look back at our style-trailblazing moms, past and present. With these personal family snaps, we present an epic roundup of our moms — and the fashionable wisdom they've imparted over the years. Paving the way for us in rad '70s wares, shoulder pads, and bikini tops, just keep clicking to get in on the Mother's Day love.

Not all Met Gala red carpet appearances are created equal, and the style-setting veterans that make their way up those iconic museum stairs in stunning couture gowns year after year have certainly left an impression. Clearly, we can't get enough. We're talking specifically about an elite group of women who have entered into a veritable Met Gala "hall of fame" by virtue of their consistent on-point dressing. Whether your mind goes first to Gwyneth Paltrow's blue Gucci snakeskin dress in 1999, conjures up images of a very Carrie Bradshaw-esque Sarah Jessica Parker in Halston, remembers Blake Lively and Karl Lagerfeld arm in arm in 2011, or jumps right to Beyoncé's flame-embroidered custom Givenchy gown from this year's festivities, you'd be right to assume that these A-listers are among the best dressed (and most memorable) in Met Gala history. Welcome to our official Met Gala Hall of Fame — click on to see who has been inducted.

As the Star Trek Into Darkness promo tour unfolds, we're privy to double the leading-lady glamour, all thanks to Zoe Saldana and Alice Eve. Zoe's latest ensemble — a floral-printed Antonio Berardi suit in a black and white palette — is far less fancy than her red-carpet styles, but just as impressive. Before that, at the Mexico City premiere, Zoe stunned in a white Elie Saab jumpsuit, while Alice took a darker approach in her sheer Gucci LBD. Before that, both starlets stunned all over Europe in a mix of Vionnet, Calvin Klein, Balmain, Reem Acra, and Emilio Pucci. To stay caught up on it all, keep clicking.

This year's Met Gala attendees gave us good reason to think two outfits are better than one. And who can blame Ashley Greene for trading her dramatic Marchesa gown for something a little shorter come afterparty? Those iconic Met stairs (read: not ornate-dress friendly) alone could prompt an outfit change, but we think it gives this A-list set another chance to show off one more great look before night's end. Case in point: Allison Williams's surprising dark and sexy twofer, courtesy of Altuzarra. Or how about Madonna's Givenchy Haute Couture tartan and fishnets getup that turned into just fishnets all over? The beauty of seeing fashion's finest is actually seeing them at their finest, and that means outfit changes galore. Which stars were bona fide Met Gala quick-change artists? Find out right this way.
