Hailee Steinfeld is ready for business in a slate gray blazer and shorts as she leads stars at the Thom Browne show for New York Fashion Week

She's been causing a storm at New York Fashion Week with her stylish and elegant ensembles.

And Hailee Steinfeld didn't let up on Saturday as she arrived at the Thom Browne show in a chic suit with shorts.

The 24-year-old actress was joined by several high-profile attendees, including the Spanish singer Rosalia, Anna Wintour and 13 Reasons Why actress Tommy Dorfman.

Hailee was attired in an outfit splitting the distance between a business suit and school uniform.

She had on a cropped white dress shirt buttoned to the top and tie-free, which showed off a hint of her taut midriff. 

The 5ft8in beauty wore a short gray blazer over it that featured sleeves that were oddly short, leaving plenty of her shirt sleeves visible.

She matched the jacket to a set of pleated and cuffed gray shorts to put the focus on her elegant legs.

The True Grit star stood tall in pointy black heels and carried a thick, angular black handbag. 

Hailee rounded out her look with red, white and blue armbands over her jacket sleeves, which may have been a patriotic nod to the day's date, the 20th anniversary of the September 11 terrorist attacks in New York City.

Rosalía arrived at the show in a hypnotizing black-and-white plaid blazer enlivened by strips of red, which she wore draped over one shoulder.

She also had on a casual white ribbed tank top that was tucked into a matching plaid skirt that reached down to her knees.

The songstress towered in chunky white platform loafers, and her brunette hair was parted down the middle and tied back in a bun so as to frame her slim black sunglasses.

Like Hailee, her outfit featured red, white and blue stripes, this time as the trim on her jacket. 

Vogue Editor-in-Chief Anna Wintour looked as elegant as ever in a long white dress decorated with a red, orange and black U-shaped pattern.

She belted the dress around her slim waist and wore gray snake-print boots.

The fashion legend was masked up for the event to help slow the spread of the novel coronavirus, and she showed off her instantly identifiable blond bob.  

Many of the show's attendees deemphasized colors and focused on classic black-and-white designs.

Tommy Dorfman of 13 Reasons Why fame put on an ornate display in a dress with a black-and-white plaid pattern.

Her outfit had thick leaf-like waves of fabric stitched onto the sides to add to its intriguing design.

She wore pointy white lace-up heels and carried a cute black dachshund-shaped handbag.

M.J. Rodriguez, who starred on FX's acclaimed series Pose, rocked a long white button-up shirt that reached down to her thighs.

She wore an apron-like skirt with a black-and-white gingham pattern over it and sported black patent leather heels with ribbed white socks.

The actress had a gingham blazer with a thicker pattern slung over her shoulder, and she matched Tommy's dog bag with an even larger design in the same shape.

Ella Emhoff, the step-daughter of Vice President Kamala Harris, looked intriguing in a two-patterned suit with baggy pants.

Half featured thick navy-and-gray stripes, while the other have featured a rougher material with gray-and-black stripes.

She wore a tie with her white shirt and had on gray-and-black derby shoes.

Ella held hands with her boyfriend Sam Hines, an editor at GQ.

He contrasted a stately charcoal suit jacket with a lighter gray pleated skirt and black boots. 

Inside the show, Lindsey Vonn, Dan Levy and Maisie Williams all show off their edgy looks.

Lindsey was draped in a black and white plaid jacket that was draped over her shoulders, and she paired it with a matching vest and pants.

Dan looked dapper in a dark blazer, but it got an intriguing touch with extra gingham patches that looked as if they'd been excavated from below the surface.

Maisie rocked a charcoal pinstripe suit with striking gray flowers stitched around the outfit, and her bleached eyebrows gave her an eerie look. 

Although many of the guests didn't wear masks outside, they're required to wear their masks inside at all times unless they're walking in the show as part of New York Fashion Week's strict Covid-19 protocols.  

Attendees are being tested for Covid-19 and undergoing regular temperature checks, and many events are require proof of vaccination for entrance.  

Individuals who feel sick or are experiencing various coronavirus symptoms are being asked to remain home during the week.
