Kate Bosworth has always presented a convincing case for the "less is more" mentality when it comes to style, and her elegant look at the Jason Wu's Boss show was no exception. She kept things streamlined and simple in a frosty, pale blue dress with a romantic, pleated sheer overlay. A shiny, slicked-back chignon showcased glowy, dewy skin (the same we've seen all over the runways this past week) and a peachy pink lip. A classic black clutch, nude nails and unfussy ankle strap sandals that prove the black and white trend is here to stay finished off the polished and pristine look.

"It" Brit Alexa Chung usually downplays her often-praised sense of style, but her latest Fashion Week look at Marc by Marc Jacobs proves she has a knack for nailing the perfect mix of downtown edge and girly glam. Tucking a patterned button-up blouse into a pink patent pencil skirt seems simple enough, but what really makes this a winning outfit is the styling: A black choker necklace, a pair of on-trend lace-up shooties, dark nail polish (one of her namesake Nails Inc. shades, we're sure) and her signature bedhead hair all keep the polka dot print and cotton candy color from looking too saccharine.

Jamie Chung is a practiced front row veteran -- it isn't out of the ordinary to spot her in the VIP section several times a day. Unsurprisingly, she's been on-trend since she started making her Lincoln Center rounds last week, but her recent romantic look at the Lela Rose show really caught our eye. Many celebs have been going the monochromatic route with tailored, suit-inspired separates, but Chung added a feminine touch to the trend with flowy silhouettes -- a silky, low-cut blouse; a floral detail skirt that's just begging for a twirl and fall's new take on summer's popular kimono. Different patterns in the same color palette and a pair of understated black ankle strap sandals flawlessly pull the whole look together. Not to mention, we're always on-board with an ensemble that looks as comfortable as a set of silky PJs.

Alexander Wang's show has become one of the most anticipated events of New York Fashion Week, but this around, Rihanna stole the spotlight well before any models came down the runway. That's saying something, considering Wang's signature star-studded front row also sat rappers Nicki Minaj and Tyga, their R&B cohort Miguel, ravers Die Antwoord and Sonic Youth's Kim Gordon side by side. RiRi turned heads in an oversized midnight blue dress-jacket and a matching iridescent fisherman's hat we're 99 percent sure only she could pull off. She finished off the look with her signature red statement lip, long red nails, bold jewelry and one of Wang's Spring/Summer 2015 handbags. In terms of guest list and collection compatibility, Wang hit this one out of the park.

It's Fashion Week and amazingly, we're talking about the other Delevingne. Poppy, older sister to "It" model Cara, sat front row at the famously flamboyant and vibrant brand Desigual, and it was a match made in heaven. While her front row cohorts Rosario Dawson and Olivia Palermo stuck with chic, monochromatic outfits, Delevingne made a statement in a mini LBD covered in luscious lips. She topped off the look with a playful mini purse covered in stars, suede ankle boots and a bright red statement lip of her own that clashed with the pink lip prints in the best way possible. We're often reminded that fashion should be fun, and Delevingne is arguably having the most fun at Fashion Week so far.
