Taylor Swift has spent years perfecting a signature: tea dresses, a red lip, winged liner and the occasional grandma shoe. This week she put a leather jacket over all of it.

For Travis Kelce's 37th birthday, the newlyweds went out for a celebratory dinner at Torrisi in New York City, Harper's Bazaar reports. Swift's outfit was darker and edgier than usual, and Vogue promptly called it her version of "bad girl style." Here is every piece she wore, what it costs and how to recreate the look for less.

The Saint Laurent leather jacket

The star of the outfit was an oversized leather jacket from Saint Laurent. Harper's Bazaar describes a wide blouson shape with a shirred, belted waistband that creates a cropped, slouchy silhouette, plus a concealed zipper hidden under a snap-button flap and a double collar, one pointed and one stand.

Swift wore both collars down and left the jacket open to show the dress underneath. Harper's Bazaar lists the jacket at $7,400 at Saks Fifth Avenue.

Vogue called the jacket "Charli xcx-, or Zoe Kravitz-, or Hailey Bieber-coded," which is a long way from the floral, feminine pieces Swift is usually photographed in.

The black lace Simkhai dress

Under the jacket was a black lace-trimmed Simkhai midi, which Harper's Bazaar identifies as the Zinnia Lace Cashmere Midi Dress, priced at $895. It is sleeveless and knit from soft, lightweight cashmere, with a V neckline and a matching V-shaped low back.

Simkhai appears to be Swift's go-to label for celebrations right now. Days earlier, she wore an off-the-shoulder plaid Simkhai minidress, cinched with a Saint Laurent chain belt and worn with Burberry knee-high boots, to support her best friend Dakota Johnson on Saturday Night Live, Vogue reports.

The shoes, bag and ring

Swift kept one foot in summer. Her black strappy heels were the Jimmy Choo Azie leather sandals, according to Vogue, and Harper's Bazaar notes she previously wore the same pair to dinner in London in May.

She added a slouchy bucket bag from Givenchy and her Kindred Lubeck engagement ring, Vogue reports. The overall effect was what Harper's Bazaar called "transitional dressing": a cold-weather jacket over a warm-weather sandal, tied together by a little black dress.

Is this a new Taylor Swift style era?

Vogue thinks it might be. The magazine points out that Swift has been "loosening the reins" on her long-time formula, from Kansas City Chiefs tank tops to this leather-and-lace mood. She has not abandoned the glamour, though: at the VMAs last month she wore a midnight-blue velvet and silver-sequined Tamara Ralph gown.

Vogue also floated a theory. Swift and Dakota Johnson recently worked together on the music video for Swift's single Patient Zero, and the magazine wonders whether Johnson's more vampish style has rubbed off on her after-dark outfits.

How to get Taylor Swift's date-night look

You do not need a $7,400 jacket to borrow the idea. The formula is simple and works for an autumn dinner anywhere.

Start with a slip or lace midi dress in black. A V neckline keeps it elegant, and a knit or cashmere fabric adds warmth without bulk.

Add an oversized, cropped leather jacket. Look for a blouson cut with a gathered or belted hem, which gives the slouchy shape without swallowing your frame. Wear it open so the dress shows.

Keep the shoes minimal. Thin-strapped black sandals balance the heavy jacket and stop the look from feeling too tough.

Finish with one soft, slouchy bag and keep jewellery to a minimum. Swift's red lip and winged liner make the outfit feel like her; your own signature beauty look will do the same for you.
