THIS HALF-UP TOPKNOT TUTORIAL IS SUPER-SIMPLE

Beauty tutorials are big on YouTube — a search for "makeup tutorial" and "hair tutorial" yields more than five million videos. In this weekly series, we put a mix of popular and under-the-radar tutorials to the test and show you what's best.

Beauty blogger and bona-fide influencer Marianna Hewitt is a master of Insta-girl hair. And often, that means a perfectly imperfect half-up topknot, the ultimate second-day-after-a-shampoo look. In a video tutorial, she breaks down exactly how she creates the style — and it's super easy.

The key to nailing any half-up look is to keep in mind that it shouldn't really be a half-up look. In other words, rather than scooping up 50 percent of your hair into the topknot, aim to leave the bulk of your hair down, and only pull up the very top, front section. To find out how Hewitt creates the rest of the look, watch the full video above.

MINIMALIST, COOL-GIRL JAPANESE LABEL ENFÖLD ARRIVES STATESIDE

It's pretty inspiring — and rare — to see sales floor staff climb the ranks to end up on the design end of the fashion industry, but Mizuki Ueda achieved just that, and without a formal education. As the creative director of Enföld, a Tokyo-based contemporary womenswear line launched in 2012, Ueda sought to offer a wardrobe of easy-to-wear, conceptual basics for busy women who wanted to look polished and refined. (The brand refers to this as "casual elegance.")

When I meet Ueda at the opening of the brand's first U.S. store in New York City's West Village (Enföld already had a wholesale operations within the Asian and European markets), she tells me via a translator that there is no specific person or muse she keeps in mind when designing. "I want women to explore the [different] combinations to find her own [way to wear the clothes]," she says. "It's meant to be for different types of women, size-wise and age-wise. What is important for her is to make women look good, while being relaxed." 

As a whole, the brand prides itself on using high-quality fabrics — the majority of which are produced locally in Japan, with a selection sourced from Italy — to create conceptual, fashion-forward pieces; it's not terribly unlike the Japanese school of thought for which designers Rei Kawakubo and Chitose Abe are also known. "The theme changes all the time, but what is consistent is the three-dimensional aspect and construction," says Ueda, whose label is also carried at Tokyo-based department stores Isetan, Mitsukoshi and Barneys New York Japan, as well as in several brand boutiques across Japan. "We're already known as a 'minimal' clothing brand [in Japan], but with the new collection, we wanted to show that we also have more detailed clothes," says Ueda, whose spring collection features more color and abstract silhouettes than seasons past. "Starting with [the] New York [store], we wanted to be known for the mix of detailed styles and minimal designs."

LET NAOMIE HARRIS'S SILVER GUCCI SUIT SHOW YOU HOW TO DRESS FOR THE HOLIDAYS

When the holidays roll around, it's easy to fall into the trap of wearing nothing but red, green and enough sparkle to help the FAA land a 747 in an electricity outage. 

Not that there's anything wrong with glitter, per se — it's just that sometimes you're looking for a chic alternative to all that shine for your holiday party circuit. Enter: Naomie Harris at the 20th Annual Holiday Film Awards in Los Angeles on Sunday night. In her silver Gucci suit, Harris looked seasonally appropriate without feeling at all costume-y. The set is strong enough on its own, so Harris smartly pairs it with a mirrored minaudière and black pointed-toe pumps, while messy up-do and silvery smokey eye kept things from feeling too corporate. It's like a how-to for holiday party dressing at just about any occasion — even work, just add a top underneath the jacket. (Or don't! We're not HR.)

KRISTEN STEWART AND ST. VINCENT ARE NOW RED CARPET OFFICIAL

Looks like art—rock dream-girl St. Vincent (née Annie Clark) is officially dating actress Kristen Stewart and, in turn, no longer dating model-who-acts-now Cara Delevingne. Rumors of Clark and Delevingne's split first flooded the internet last month, but weren't truly confirmed until just two weeks ago when images surfaced of Clark and Stewart spending time together in New York. There was also, of course, an accompanying Us Weekly story in which a "source" told the magazine that "it's been very romantic."

And on Wednesday at the 2016 CFDA/Vogue Fashion Fund Show at Los Angeles's Chateau Marmont, the brand-new pair made their first red-carpet appearance. For the occasion, Stewart wore ankle-length gingham trousers, embellished loafers, a black blazer and Ray-Ban Wayfarers, with her platinum bob slicked back; meanwhile, Clark wore a cropped tweed jacket, billowing trousers and satin mules from Chanel, a neckerchief and an extra-long pendant necklace. It's also worth noting that, while seated in the front row for the runway show, Stewart daintily held onto a stem of what appears to be pink freesia — a pleasant accessory.

Beyond fashion's new favorite "It" couple, the event attracted quite the celebrity crowd. Clark and Stewart were seated next to Emma Stone and Katy Perry, while models Rosie Huntington-Whiteley, Alessandra Ambrosio,Jourdan Dunn and Amber Valletta posed for pictures elsewhere. Michelle Monaghan looked awesome in a pair of wide-legged, light-wash jeans, whileCiara made her first official appearance since announcing her pregnancy on Wednesday.
