The easiest hair trend to come out of Paris this season doesn't need a single new product. At Balenciaga Spring 2027, models wore their hair tucked into the collars of their coats and jackets, and the move has a name: the Olsen tuck. Grazia, in its round-up of the hair and beauty trends that ruled Paris Fashion Week Spring/Summer 2027, called it "the easiest beauty trend of the season," one that "needs no new product or salon appointment." Here's where it comes from and exactly how to do it now.

What Happened at Balenciaga Spring 2027

Pierpaolo Piccioli showed his third ready-to-wear collection for Balenciaga on 1 October at the Tennis Club de Paris. WWD reported that Piccioli carried a couture stitching technique from his haute couture gown into everyday shirts, T-shirts and leather jackets. On shirts, that dense stitching on the collar and yoke created "a softer version of a stand-up collar, while adding a bit of texture and subtle sheen near the face." Harper's Bazaar also singled out a leather jacket with "a severely sculpted bodice and an elaborate funnel neck."

That focus on collars is the backdrop for the hair. According to Grazia, the tucked hair created "the illusion of a shorter cut and a casually chic, undone finish," and it echoed Piccioli's thinking for the season: "let your clothes do all the work." The designer described his own goal to WWD as "Changing the silhouette, and the feeling and attitude of the clothes, but not changing their authenticity." The tuck does the same thing for hair: same length, new shape.

What Is the Olsen Tuck, Exactly?

Vogue defines the Olsen tuck as "a hybrid beauty-and-fashion look where you tuck the ends of your hair into the collar of your top." Its origin story, as Vogue tells it, is purely practical. It was likely born when someone asked, "Where do I put all of my hair when I'm wearing something with a big collar?" It is named after Mary-Kate and Ashley Olsen, the founders of The Row, who have been photographed wearing it many times.

The twins aren't the only reference. Marie Claire points to Phoebe Philo, who often wore her hair tucked into a turtleneck for her post-show bows at Celine. Edward Kanarecki, the curator behind the @phoebephiloarchives Instagram account, told the magazine it's "a distinct, instinctive, and nonchalant gesture that's trademark Phoebe."

The term itself took off online. Marie Claire reported in November 2024 that TikTok had named the move the "Olsen Tuck." A year later, Bustle noted that the trick was back in the spotlight after Sydney Sweeney tucked her long blonde hair into a moto jacket in a GQ interview. Elle Fanning wore it front row at Coach in September 2025, per Vogue. The tuck has walked runways before (Vogue notes models at Khaite wore it with big shearling collars), but Balenciaga's spring outing makes it a warm-weather trend too.

Why It's a Spring Trend Now

Until now, the Olsen tuck has mostly been sold as a cold-weather look. Vogue's guide to it focuses on turtlenecks, funnel-neck coats and oversized scarves. Balenciaga's spring collars point to a lighter version: shirts with soft stand collars and jackets with high necks. Vogue's Christian Allaire had already compared the "cool nonchalance" of fall 2026's half-tucked shirt collars, seen at Bottega Veneta, Jil Sander and Balenciaga, to the Olsen tuck.

How to Do the Olsen Tuck: Step by Step

Everything below is built from the advice in Glamour, Bustle and Vogue. You need two minutes and a collar.

Check your length. Glamour says the look works best with hair at collarbone length or longer, so there is enough hair to fold inside.Add grip, not shine. Bustle recommends a little texture so the faux bob holds its shape. That can be a spritz of texturizing spray, or simply second-day hair.Pick a part. Vogue describes the Olsen version as "flowing, center-parted strands," so a soft middle part is the classic choice.Put the top on first, then tuck. Gather your lengths loosely at the nape, then slide them down inside the collar. Don't twist them tight. You want a soft, rounded shape that sits around jaw or shoulder level.Pull out volume at the crown. Bustle reports that some people put their hair in loose pigtails before tucking, to get more lift on top and keep it from slipping out.Leave a few pieces out. With lighter tops, Bustle suggests leaving some face-framing strands out so the tuck looks "relaxed" rather than "rigid."Let it come loose. Glamour's advice: when strands slip out during the day, let them fall. "That slight messiness is what makes the 'Olsen tuck' an authentic, modern, and perfectly imperfect style statement."

The Best Collars for the Tuck

Stand-collar shirts: the most spring-friendly option and the closest to Balenciaga's softly stitched collars. Button a cotton or linen shirt to the top.Funnel-neck jackets: Vogue calls them architectural and fully functional, "no scarf needed." This is the Balenciaga leather-jacket version.Fine-gauge turtlenecks: Vogue recommends a soft knit that stands tall without bulk.Draped blouses: for a no-outerwear version, Vogue suggests fluid fabrics "with a gentle stand collar or soft neckline that lets hair slip in and stay put."Trench coats and blazers: Glamour lists these too. With longer hair, it says even open coats and crewnecks can work.

Does It Work on Every Hair Type?

Not always, and it's better to know that before you try. Beauty editor Samantha Holender told Marie Claire: "The Olsen tuck is a recipe for knots." She added, "You need to have a specific, fine hair texture and density for it to work. If you have thick or coarse hair, this trend won't look the same on you as it does on others." Bustle also notes that your hair will probably need a good brush once you untuck it.

There are ways around this. Glamour suggests braiding your hair first if you want to protect it from frizz or split ends, but warns against too much tension, or you'll lose the effortless effect. If your hair is very thick or curly, try a single loose, low braid inside a roomier collar, and detangle gently when you take it out.

The Advanced Version: The Hair Scarf

If the basic tuck feels too easy, there's a runway-tested next step. For Christian Siriano's fall/winter 2026 show, Elle reported that hairstylist Lacy Redway turned the hair into a scarf. She rough-dried it for natural texture and flyaways and gathered the top section into a low ponytail at the nape. Then she crossed the remaining hair from each side in front of the neck and fastened it back into the ponytail, finishing with dry texturizing spray. Elle called it "the new 'Olsen tuck.'" No collar required.

Don't Overthink It

The best advice on the Olsen tuck is a warning against trying too hard. "If you're actively tucking your hair into a sweater, you've lost the plot," Marie Claire entertainment director Neha Prakash told the magazine. That is also the point of Piccioli's Balenciaga this season: elaborate couture work made to look like an ordinary shirt. Put on the collar, push your hair inside it and leave the house. If a few strands escape, leave them.
