On Saturday evening, Christian Dior presented its Resort 2014 collection in Monaco. The principality has held special meaning for the house since 1956, when actress Grace Kelly wore a Dior gown to celebrate her engagement to Prince Rainier of Monaco.

The return to Monaco was both an homage to the house's heritage and also a signal of a new era in how (and where) the label stages its Resort collection, with plans to always take the collection abroad going forward. But this wasn't the only poignant moment to come with Saturday's showing. For the first time, Raf Simons incorporated lace into his pieces, working the fabric into everything from sheer blouses and fitted crop tops to modified coatdresses and relaxed sheaths. "I thought it's kind of old and too romantic and too tragic. And suddenly I thought, it's a challenge to make it modern and edgy and kind of futuristic," he said.

A look at the complete collection, plus our review, here in the gallery.

The 2013 Billboard Music Awards red carpet was red hot, with Selena Gomez leading the pack. The singer was one of the first to arrive — and she did so in an eye-catching neon-infused Atelier Versace gown from the label's Spring '13 collection. Also in the mix? Jennifer Lopez, Taylor Swift, Chloë Moretz, Hayden Panettiere, and a very sexy Jennifer Morrison. Of course, that's just the tip of the iceberg. Click through to see who wore what at the Billboard Music Awards.

The bridal trends for Spring 2014 leave room to try something a bit different. While gorgeous white gowns and traditional strapless silhouettes certainly made their customary appearance, it wasn't all run of the mill. Vera Wang surprised with black-and-white looks, finished with dramatic black opera-length gloves. Oscar de la Renta dipped into the color wheel for a true "something blue," Reem Acra turned out cocktail minis topped with veiled umbrellas, and Carolina Herrera debuted a sexier kind of wedding-day ensemble (think deep V-front necklines). For inspiration aplenty — and a closer look at what exactly the Spring '14 bridal forecast means for your own wedding-dress search — click on.

Thank goodness it's Friday, because Doutzen Kroes's latest turn as the face of H&M's High Summer campaign makes us want to be gallivanting on some far-off shore, too. Sure, Beyoncé may have heated things up in the brand's Summer kickoff campaign, but this Terry Richardson-shot spread is all sunshine, perfectly tousled beach hair, and of course, beach-bound essentials — with Tulum, Mexico, as the backdrop. Inside, Kroes shows off a cool mix of easy cover-ups, belted and accented with statement jewelry, and truth be told, there's really not much more you need than that. A look at the H&M High Summer campaign, as well as our favorite picks from the collection, here.

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.
