The superstar, 42, teamed a blazer dress with matching boots and cowboy hat for the runway show in New York.
It came two days after announcing her country-themed album Renaissance Act II during the Super Bowl.
Beyoncé also released two tracks on Sunday, with one, Texas Hold ’Em, already topping the iTunes chart.
Last week Bey’s Super Bowl announcement shocked fans.
The singer dropped two singles from the upcoming country-leaning LP.
Beyonce dropped the news minutes after Usher performed at the Halftime Show.
“TEXAS HOLD ‘EM and 16 CARRIAGES out now,” she captioned her Instagram post.
In it, the hitmaker wore a black jacket and black hat with just a heart, hanging from a belt covering her front and a shiny bra covering her boobs.
The second photo for 16 Carriages was more tame and had a short-haired Beyonce wearing a cowboy hat and a button-down shirt.
The two songs are available on YouTube and Tidal now, and Texas Hold ‘Em is also on Spotify.
Beyonce announced the album in a Super Bowl commercial.
She sampled a portion of Texas Hold ‘Em in the commercial as she announced Renaissance act 2 would be out on March 29.
“OK, they ready — drop the new music. I told y’all the Renaissance is not over,” the singer said, after scrolling through songs on her iPhone.
