When she thinks happiness, she thinks “that little black dress.”

Taylor Swift showed off plenty of party-ready ‘fits while visiting Las Vegas with Travis Kelce last weekend, and new photos from one of her nights out revealed a sassy leather look.

The “Fortnight” singer, 34, is only visible from the back in the pic, which were shared on X (formerly Twitter) by a fan account and captioned, “Taylor and Travis out in Vegas on Friday night.”

In the snaps, Swift wears an ultra-short black minidress with long sleeves as she walks hand-in-hand through the Aria Resort & Casino with the Kansas City Chiefs tight end.

She appears to be wearing Norma Kamali x Revolve Grace minidress ($245), which is crafted from vegan leather and features an off-the-shoulder neckline.

She paired the dress with black slingback heels and a what appeared to be a burgundy crystal-covered Stella McCartney bag ($1,175), wearing her hair in a half-up style.

Meanwhile, Kelce, 34, sported a peach tracksuit for their fun night out, when they joined his teammate, Patrick Mahomes, 28, and the quarterback’s wife, Brittany Mahomes, 28, at Easy’s Cocktail Lounge.

Another fan shared a closeup pic on X Wednesday night captioned, “this is easily one of taylor’s best looks and i can’t even see it fully.”

Swifties went wild for the look, like one who wrote, “You’re not lying! She is serving in that dress! Leather looks good on her and it fits her like a glove! I wish we could see the front!”

“Like excuse me @taylorswift13 may I please borrow that dress when you are done with it?!” another fan commented.
